Before the universal the nomenclature system was introduced in organic chemistry, major polymers were given a name, STYRENE being one of them (e.g.polystyrene). So was VINYL, as in Poly Vinyl Chloride (? flexi discs of the fron of NME?). Studio / EMI discs are made of a polymer ACETATE. And finally, for anorak like me, nylon is a polymer that was patented in NY & LONdon.
