【摘要】 到目前为止,交联过程之所以难以控制是因为在交联聚合体系中,没有一个与交联过程相竞争的反应。本文利用大分子在溶液中是无规线团的特征,设计了含有分子内和分子间反应的交联聚合体系,分子间反应即交联过程,而分子内反应使分子间反应受到抑制,使交联过程的链增长不能无限发展,从而合成了可溶解的具有交联结构的大分子。更多还原

【Abstract】 Up to now, to control the cross-linking process is still difficult in the cross-linking polymerization system, because there is not a competitive reaction against the cross-linking process. In this paper the feature of random coil type morphology of macromolecules in solution is used to design a cross-linking polymerization system consisting of inter- and intramolecular reactions. The intermolecular reaction is the cross-linking process, while the intramolecular reaction makes the intermolecular reaction controlled. So the chain growth of the cross-linking process is prevented from unceasing development, as a result the soluble cross-linked macromolecules are synthesized.更多还原
