History and Evolution of Vinyl
History and Evolution of Vinyl Polyvinyl chloride or PVC was first created by the German chemist Eugen Baumann in 1872. Eugen Baumann never applied for a patent. Polyvinyl chloride or PVC was never patented until 1913 when German, Friedrich Klatte invented a new method of the polymerization of vinyl chloride using sunlight. Friedrich Klatte became the first inventor to receive a patent for PVC. However, no really useful purpose for PVC was found until Waldo Semon came along and made PVC a better product. Semon had been quoted as saying, People thought of PVC as worthless back then [circa 1926]. Theyd throw it in the trash. Waldo Semon - Useful Vinyl In 1926, Waldo Lonsbury Semon was working for the B.F. Goodrich Company in the United States as a researcher, when he invented plasticized polyvinyl chloride. Waldo Semon had been trying to dehydrohalogenate polyvinyl chloride in a high boiling solvent in order to obtain an unsaturated polymer that could bond rubber to metal. For his invention, Waldo Semon received United States patents #1,929,453 and #2,188,396 for the Synthetic Rubber-like Composition and Method of Making Same; Method of Preparing Polyvinyl Halide Products. All About Vinyl Vinyl is the second most produced plastic in the world. The first products from vinyl that Walter Semon produced were golf balls and shoe heels. Today, hundreds of products are made from vinyl, including ââ¬â¹shower curtains, raincoats, wires, appliances, floor tiles, paints and surface coatings. According to the Vinyl Institute, like all plastic materials, vinyl is made from a series of processing steps that converts raw materials (petroleum, natural gas or coal) into unique synthetic products called polymers. The Vinyl Institute states that vinyl polymer is unusual because it is based only in part on hydrocarbon materials (ethylene obtained by processing natural gas or petroleum), the other half of the vinyl polymer is based on the natural element chlorine (salt). The resulting compound, ethylene dichloride, is converted at very high temperatures to vinyl chloride monomer gas. Through the chemical reaction known as polymerization, vinyl chloride monomer becomes polyvinyl chloride resin that can be used to produce an endless variety of products.

These famous people failed at first, then found success
These famous people failed at first, then found success Ever get discouraged because you feel like nothingââ¬â¢s going your way? Or maybe youââ¬â¢ve been at it for a few years and just feel that you arenââ¬â¢t where you should- or want to- be. Chances are, youââ¬â¢re being too hard on yourself and not allowing for the normal ebb and flow of failure that leads to most success. Donââ¬â¢t believe it? We have proof. Here are 10 people who totally failed at first and then went on to achieve great success, fame, and fortune! Use them for inspiration when next youââ¬â¢re getting down on yourself.1. R.H. MacyYou probably donââ¬â¢t know this guy by name alone, but chances are youââ¬â¢ve shopped at one of his stores. Thatââ¬â¢s right, the founder of Macyââ¬â¢s department stores managed to fail at seven early business attempts before landing on the perfect breakthrough with his first NYC store.2. Bill GatesFirst, he dropped out of Harvard. Then, his first business was a failed company youââ¬â¢ve likely never heard of called Traf-o-Data. But his next company, Microsoft, did much better. Much,à much better.3. Albert EinsteinAs a kid, Einstein didnââ¬â¢t speak until he was four years old. In fact, he couldnââ¬â¢t read until the age of seven- his parents and teachers thought he might not be very bright at all. He was expelled from school and denied admission to Zurich Polytechnic. But then he went on to become such a success in his field that his name is now used as a synonym for ââ¬Å"geniusâ⬠all over the world.4. Steven SpielbergSpielberg was rejected from USCââ¬â¢s School of Theater, Film, Television three times, then dropped out of Cal State, Long Beach. He eventually went back and finished school in 2002, but only after becoming the big-budget award-winning smash success he is today.à 5. J.K. RowlingThe billion dollar empress of the Harry Potter franchise? She was a divorced, depressed, and penniless single mother attending school while on welfare. Now sheââ¬â¢s one of the richest women in the world.6. Tyler PerryFrom a rough abusive childhood, high school expulsion, and two attempted suicides, Tyler Perry went on to work several jobs and try to build his career. At one point, he sunk everything he had into his first film, which flopped spectacularly. He kept at it, though (even sleeping in his car) and now heââ¬â¢s one of entertainmentââ¬â¢s most respected and highest paid men.7. Emily BluntThe award-winning acclaimed actress had a terrible stutter until the age of 14. But Blunt was encouraged to do theatre, which changed everything. Through hard work and gigs that asked her to play different characters and use different accents, she was able to overcome her stutter and become an international film star of the first degree.8. Vera WangFashion designer Vera Wang failed first at figure skating when she didnââ¬â¢t make the 1968 Olympic team. She then became a Vogue editor, but was passed over for a coveted promotion. At the age of 40, she s tarted designing wedding gowns and, well, the rest is history. Sheââ¬â¢s now worth over a billion dollars. Sheââ¬â¢s even come full circle by designing costumes for Olympic figure skater Nancy Kerrigan.à 9. Lucille BallEveryone loves ââ¬Å"Lucy,â⬠but before this sitcom star was tearing it up with husband Desi Arnaz on cable, she was considered the ââ¬Å"Queen of B Moviesâ⬠because the only work she could get was on second-tier films people found silly. Sheââ¬â¢s now remembered as one of the funniest and most accomplished comediennes of all time.
