I was surprised a few years ago to see that RCA used Vinyl on their LP discs of the early thirties. In many places, the material for those Program Transcriptions was identified as "Victrolite" whatever that was supposed to have been. But, I have the RCA Victor dealer fact book from 1932, where the Long Playing records were anounced, and they said that the discs were made of "Vinylite". It's really interesting how vinyl plastics ahve been around, in one form or another.

On both occasions the polymer appeared as a white solid inside flasks of vinyl chloride that had been left exposed to sunlight. In the early 20th century the Russian chemist Ivan Ostromislensky and Fritz Klatte of the German chemical company Griesheim-Elektron both attempted to use PVC (polyvinyl chloride) in commercial products, but difficulties in processing the rigid, sometimes brittle polymer blocked their efforts. Waldo Semon and the B.F. Goodrich Company developed a method in 1926 to plasticize PVC by blending it with various additives. The result was a more flexible and more easily processed material that soon achieved widespread commercial use. > Wiki can be a wonderful (if not reliably trustworthy) thing! > > > > > From: esrobe...@hotmail.com > > To: phono-l@oldcrank.org > > Date: Fri, 19 Nov 2010 17:49:04 +0000 > > Subject: Re: [Phono-L] Really Vinyl? > > > > > > I think the Victor picture discs had something more durable than what the HotW discs used. It's like a clear/hazy vinyl surface, easy to see and get a feel for if you have a broken Victor PD. Vinyl certainly existed in the 30's, didn't it? > > > > > > > From: maxbu...@wowway.com > > > To: phono-l@oldcrank.org > > > Date: Fri, 19 Nov 2010 11:42:03 -0600 > > > Subject: [Phono-L] Really Vinyl? > > > > > > I was under the impression that vinyl came along some time after picture > > > discs came on the scene.
