摘要： The present invention relates to a process for precipitation polymerization of Alpha -methylstyrene in a hydrocarbon medium in which poly- Alpha -methylstyrene is insoluble or only little soluble. The polymerization is initiated by a finely divided alkali metal which is used together with certain phosphoric acid amides or ethers or mixtures thereof as polymerization accelerators.

摘要： Living monolithio polymers are coupled by the action of certain novel coupling agents (e.g., nitrobenzene, sulfur, dimethyl terephthalate, acrylonitrile, maleic anhydride). For example, styrene is first polymerized in benzene with n-butyl lithium catalyst to form a styrene polymer block (S) followed by addition of butadiene to form a butadiene polymer block (B) copolymerized with the styrene block in the form of a living monolithio block copolymer SB- Li+. Then a coupling agent, such as nitrobenzene, is added, forming coupled block copolymer SBCSB where C is a residue of the coupling agent. Coupling of three molecules of living polymer is possible with maleic anhydride, or of four molecules with dimethyl terephthalate.
摘要翻译：活性整体聚合物通过某些新型偶联剂（例如硝基苯，硫，对苯二甲酸二甲酯，丙烯腈，马来酸酐）的作用而偶联。例如，苯乙烯首先在苯中用正丁基锂催化剂聚合以形成苯乙烯聚合物嵌段（S），然后加入丁二烯以形成与苯乙烯嵌段共聚的丁二烯聚合物嵌段（B）嵌段共聚物SB（ - ）Li（+）。然后加入偶联剂如硝基苯，形成偶联的嵌段共聚物SBCSB，其中C是偶联剂的残基。三分子活性聚合物与马来酸酐或四分子与对苯二甲酸二甲酯的偶联是可能的。
