A non-tacky thermoplastic elastomeric composition which is an optically clear blend of (A) a copolymer of ethyl or butyl acrylate or mixtures thereof with from 2 to 10% by weight of a copolymerizable ethylenic monomer containing an acid group and (B) from 2 to 15%, by weight of the blend, of a water-soluble homopolymer of a vinyl lactam having the structure <IMAGE> 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 lactam with from 1 to 80 mole percent of a copolymerizable monomer containing a polymerizable ethylenic unsaturation, the vinyl lactam polymer or copolymer having a glass transistion temperature from 20 DEG to 250 DEG C.
