Functionalized degradable ROMP (ring-opening metathesis) polymers and methods, starting monomers and synthetic monomeric and polymeric intermediates for preparation of such functionalized polymers. More specifically, monomers having a bicyclic oxazinone structure, a bicyclic urea, or a heteronorbornene core structure, among others, have been found to be substrates for ROMP polymerization. ROMP polymers prepared from these monomers have been found to be both acid and base labile. Additionally, the monomers can be chemically modified at a site distal to the polymerizable moieties and bridgehead carbons. The properties of the resulting polymers and copolymers can be tailored without destabiling the monomer. Polymers and copolymers of the invention are degradable but have a glass temperature of 100° C. or more.
可降解的功能化ROMP(环开放重聚合)聚合物及其制备方法、起始单体和合成单体和聚合中间体,用于制备这种功能化聚合物。更具体地说,已发现具有双环氧氮杂环结构、双环脲或杂环辛烷烯核心结构等单体是ROMP聚合的底物。从这些单体制备的ROMP聚合物已发现既具有酸性又具有碱性的不稳定性。此外,这些单体可以在可聚合基团和桥头碳远离的位置进行化学修饰。所得聚合物和共聚物的性质可以定制而不破坏单体。发明的聚合物和共聚物可降解,但具有100℃或更高的玻璃转移温度。
