A process for producing a styrenic copolymer having a functional group and the syndiotactic configuration is provided. The process comprises bringing a metal compound into interaction with a vinyl compound having a functional group to mask the functional group and copolymerizing the vinyl compound having the masked functional group with a styrenic compound in the presence of a polymerization catalyst comprising (A) a transition metal compound, (B) at least one compound selected from compounds having oxygen and compounds which can form ionic complex compounds by reaction with the transition metal compound and (C) an organometallic compound. A styrenic copolymer which is a random, block or graft copolymer, preferably a random copolymer, of a vinyl compound having a functional group and a styrenic compound and has the repeating units derived from the styrenic compound having the syndiotactic configuration can be produced efficiently.
The above styrenic random copolymer exhibits excellent physical properties such as excellent adhesion with various adhesives and excellent compatibility with various rubbers and is advantageously used for various applications as various types of molded articles.
本发明提供了一种生产具有官能团和辛二构造的苯乙烯共聚物的工艺。该工艺包括使金属化合物与具有官能团的乙烯基化合物相互作用以掩蔽官能团,并在聚合催化剂存在下使具有被掩蔽官能团的乙烯基化合物与苯乙烯化合物共聚,聚合催化剂包括(A)过渡金属化合物,(B)至少一种选自具有氧的化合物和通过与过渡金属化合物反应可形成离子络合物的化合物的化合物,以及(C)有机金属化合物。一种苯乙烯共聚物是由具有官能团的乙烯基化合物和苯乙烯化合物组成的无规、嵌段或接枝共聚物,最好是无规共聚物,其重复单元来自具有联合构型的苯乙烯化合物。
上述苯乙烯类无规共聚物具有优异的物理性能,例如与各种粘合剂具有优异的粘合性,与各种橡胶具有优异的相容性,可用于各种成型制品。
