“…For our system, it was determined to be 8.5 x 10-5 and was in very good agreement with literature values given for polystyrene samples. The values of K 2 and R;/(1) for the AIBN initiated polymerization of p-methylstyrene are 2.5xl0-8 lmol-1 s-2 and 4.46x 10-3 s-1 , respectively, as obtained from the data of Muncshler et al 12 It should Polymer J., Vol. 21, No.…”

ABSTRACT:A new polymeric peroxycarbamate (PPC), having a substituted cycloaliphatic moiety, was synthesized using the corresponding diisocyanate and a dihydroperoxide. The thermal decomposition kinetics of this PPC were studied in 1,4-dioxane solution at 80, 90, and I00°C. The decomposition reaction was found to proceed according to first order kinetics with activation energy of 125 kJ mo! -1 . Furthermore, this PPC was used to initiate the bulk polymerization of methylstyrene at 80°C and shown to be an effective initiator with negligible chain transfer to the initiator.

The bulk polymerisation of styrene, 4-methoxystyrene and 4-methylstyrene was investigated at 60 "C using 2,2'-azoisobutyronitririle (AIBN) as the initiator. Initial rates (RY) and efficiencies (f) of initiation were calculated from the radioactive content of the polymer obtained by labelling the initiator as either [methyl-'4C4]AIBN or [cyano-I4C2]AIBN. Rates of polymerisation determined gravimetrically are in good agreement with rates determined by the dilatometer technique. An empirical linear relationship between the number of initiator fragments and the degree of monomer conversion was noted. Factors affecting the termination of polymer radicals are discussed and compared with other published work. The polymerisation reaction is terminated predominantly by combination in the case of all three monomers, and chain transfer constants to initiator and to monomer are of the order of and respectively. a) part 1: cf. ref.23) b, Submitted by A.
