These compounds contain an oxetane functionality and a cinnamyl functionality. The oxetane functionality is homopolymerizable in reactions that can undergo cationic or anionic ring opening, and the cinnamyl functionality is polymerizable with compounds such as electron acceptor compounds. The dual functionality allows for dual cure processing. The generic structure of such compounds is
in which R is a methyl or ethyl group, X and Y independently are a direct bond, or an ether, ester, or carbamate group, and Q is a divalent hydrocarbon (which may contain heteroatoms of N, O, or S), provided that X and Y will not both be direct bonds in the same molecule.
这些化合物包含一个氧杂环辛烷基和一个肉桂基。氧杂环辛烷基在可以发生阳离子或阴离子环开反应的情况下是同聚合的,而肉桂基可以与诸如电子受体化合物等化合物聚合。双重功能允许双重固化处理。此类化合物的通用结构如下,其中R是甲基或乙基基团,X和Y独立地是直链键,或醚、酯或碳酸酯基团,Q是二价碳氢化合物(可能含有N、O或S杂原子),前提是X和Y不会同时是同一分子中的直链键。
