Abstract
Copolymers of 1,2,2,6,6-pentamethyl-4-piperidinyl m-isopropenyl-alpha, alpha-dimethylbenzyl carbamate (CB) with styrene (S) and with methyl m ethacrylate (MMA) were synthesized using AIBN as initiator. S-CB copol ymers made from feed ranging from 0.45-0.94 mole fractions S and MMA-C B copolymers made from feed of 0.34-0.88 mole fractions MMA were used to determine the monomer reactivity ratios r1 and r2. The structure of S-CB copolymers was inferred to be mainly of a random nature and in t he MMA-CB copolymerization system there is a stronger tendency to form alternating copolymers.
