| Abstract: | Anionic polymerization can produce branches with low molecular weight and narrow molecular weight distributions. Post polymerization linking involving the still active chain ends can then be done to produce branched oligomers with a predetermined number of arms. These species are then excellent model compounds for testing high molecular weight branches. Here we chose the reaction of oligobutadienyllithium with ethyl acetate, dimethyl adipatc, diethyl adipatc, dimethyl phthalatcand epoxidized soyabean oil. For the last linking agent, we compared the result obtained with a high molecular weight poly(styryl-b-butadienyl)lithium. |
