Anionic Polymerization Of Methyl Methacrylate Subsumption And Their Coploymer Initiated By RLi/Ph₂PCu

This work was supported by National Natural Science Foundation of China(No.20374005) and China Petroleum & Chemical Corporation. Basing on the heterocuprates with greatly improved thermal stability and high initiating efficiency, we successfully overcoming those homocuprates' shortcomings, initiator thermal decomposition, low initiating efficiency and broad MWD etc, related polymerization of MMA. Through researching the influencing factors(eg: polymerzation temperature, various initiators and so on) on polymerization of MMA initiated by RLi/Ph₂PCu lithium organocuprates, a new way which can effectively initiate monomers including MMA, TFEMA etc and possesses the living polymerization characters has been gotten.The polymerizing progress and the ultimate polymer were influenced by the polymerization temperature, various "R" of...
