1. A crosslinked poly(ethylene or propylene) glycol-containing polymer formed by radical copolymerization of a derivatived poly(ethylene or propylene) glycol of the formula ##STR6## wherein a) n is an integer of from 4 to 2,000,b) R" is H or CH3,c) R is --(CR'"'"'2)s --(C6 R'"'"'6)t --(CR'"'"'2)u -- whereineach R'"'"' is H, alkyl, aralkyl, substituted aralkyl, aryl or substituted aryl, said substituted aralkyl and substituted aryl being ring substituted with alkyl, hydroxy, mercapto, nitro, amino, mono- or dialkylamino, or halogen;

  • d) q is zero or 1 and s, t and u each is zero or an integer of 1-10, provided that the polymer contains no ester bonds, with an acrylic compound of the formula ##STR7## wherein R1 is --CY--X--R5 or --CN, and R2, R3 and R4 each is H, alkyl, aralkyl, aryl, --CY--X--R5 or --CN, where Y is O or S, X is O, S or NR6, R5 is alkyl, aralkyl or aryl, and R6 is H or H5.
