Abstract
A polymer compsn. comprises polyacrylonitrile polymer (I) and a multiblock copolymer (II) with acrylonitrile (III) and non-crystalline polymer (IV) sequences. The ave. no. of the sequences in (II) are equal and at least 2. (III) has a mol. wt. of at least 500 and (IV) comprises at least 10 units contg. highly polar units comprising acrylamide, N-substd. acrylamide, acrylic acid, esters of acrylic acid, salts of acrylic acid, hydrazides of acrylic acid and/or glutarimide. The polymer compsn. exhibits the more desirable properties of the respective polymers, is capable of being stretched or oriented at room temps. and is capable of forming bulky articles. The conc. solns. are tough gels which can be shaped by conventional plastics methods and subsequent evapn. of the solvent.
