摘要：

This paper deals with our recent work on selective living anionic polymerization of divinylbenzene derivatives. We first successfully demonstrated that one of the two vinyl groups of p-divinylbenzene (p-DVB) exclusively undergoes selective vinyl polymerization in a living manner in THE at -78 degrees C with oligo(alpha-methylstyryl)lithium in the presence of a 10-fold excess of tert-BuOK. Indeed, we found that the obtained polymer has a predictable molecular weight and a narrow molecular weight distribution (M-w/M-n similar to 1.05). Herein, we discuss that the polymerization factors, such as counter cation, added salt and polymerization temperature, strongly affected the polymerization behavior of p-DVB. The precise synthesis of architectural polymers, such as diblock copolymer, triblock terpolymer, tetrablock quarterpolymer, and star-branched polymer containing poly(p-divinylbenzene) segments, is also described.
