Abstract
In the bulk copolymerization of 1-chloro-1,3-butadiene (CB) and styrene (St) at 70°C, the copolymerization rate, monomer reactivity ratio (MRR), and elementary reactions governing the molecular weight of the copolymer were studied. The rate of St polymerization decreased drastically by the addition of a small amount of CB, suggesting a predominant cross-over termination, (kt12). MRRs found: rCB=1.680 and rSt=0.274, hence Q=1.80 and e=0.081 for CB. The molecular weight of copolymer and its polydispersity decreased with an increase in CB concentration, which is interpreted by a large kt12 value. When the CB concentration becomes large, termination between CB polymer radicals may also become important.
