Thermoplastic elastomeric compositions

A non-tacky thermoplastic elastomeric composition comprising an optically clear blend of (A) a high molecular weight copolymer of ethyl or butyl acrylate or mixtures thereof with from 2 to 10% by weight, based on the weight of the copolymer, of a copolymerizable ethylenic monomer containing an acid group, said copolymer having a molecular weight of at least 600,000 and a glass transition temperature from -10.degree. C. to -50.degree. C., and (B) from 2 to 15%, by weight of the blend, of a water-soluble homopolymer of a vinyl lactam having the structure ##STR3## in which X represents an alkylene bridge having three to five carbon atoms, or from 2 to 30%, by weight of the blend, of a copolymer of said vinyl lactam with from 1 to 80 mole percent of a copolymerizable monomer containing a polymerizable ethylenic unsaturation, said vinyl lactam polymer and copolymer having a molecular weight of at least 10,000 and a glass transition temperature from 20.degree. to 250.degree. C.
