Notes:
Copolymers of 1,2,2,6,6-pentamethyl-4-piperidinyl m-isopropenyl-α,α-dimethylbenzyl carbamate (CB) with styrene (S) and with methyl methacrylate (MMA) were synthesized using AIBN as initiator. S-CB copolymers made from feed ranging from 0.45-0.94 mole fractions S and MMA-CB 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 the MMA-CB copolymerization system there is a stronger tendency to form alternating copolymers. © 1993 John Wiley & Sons, Inc.
