Abstract

Composition consisting essentially of: PA0 a. Poly (alkylated vinylpyrrolidone) which is a linear copolymer of: PA1 1. alpha olefin having at least two carbon atoms; and PA1 2. N vinyl monomer of the formula ##STR1## where R represents H, CH.sub.3 or C.sub.2 H.sub.5 ; and b. N-vinyl-2-pyrrolidone as diluent monomer, the N-vinyl-2-pyrrolidone being present in an amount between about 25 and about 30 wt % based on the total of N-vinyl-2-pyrrolidone and poly (alkylated vinylpyrrolidone).
