✦ Synopsis

A~tract~4-(Thiocyanatoacetyl)phenyl methacrylate (TPMA) was copolymerized with phenyl methacrylate (PMA) or styrene (ST) to poly(TPMA-co-PMA) or poly(TPMA-co-ST). These copolymers were photocrosslinked by laser u.v. irradiation (308 nm). The quantum efficiency ~b of crosslinking was determined by means of sol/gel analysis. 4, varied from 1.3.10 -3 to 7.6-l0 -3 with the copolymer composition. A linear dependence of ~b on the TPMA content was found for poly(TPMA-co-PMA).
