Procedure

An uncrosslinked vinylpyrrolidone (VP) homopolymer, a crosslinked 98/2 weight ratio vinylpyrrolidone/ethylene glycol dimethacrylate (VP/EGDM) copolymer, an uncrosslinked 70/30 weight ratio vinylpyrrolidone/lauryl methacrylate (VP/LM) copolymer and an uncrosslinked 79/21 weight ratio vinylpyrrolidone/vinyl acetate (VP/VA) copolymer were prepared by solution polymerization in cyclohexane using lauroyl peroxide as catalyst. The viscous reaction mixture was cast on a polytetrafluoroethylene sheet and the solvent was permitted to evaporate. The resultant thin film was dried at 60° C. in a forced air oven, washed free of residual monomer, if any, with petroleum ether and redried in vacuo at 60° C.
