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.
功能化可降解的ROMP(环开环聚合)聚合物及其制备方法,起始单体和合成单体和聚合物中间体,用于制备这种功能化聚合物。更具体地说,具有双环氧噁唑酮结构、双环脲或杂环诺邦烯核结构等单体已被发现可作为ROMP聚合的底物。从这些单体制备的ROMP聚合物被发现既具有酸性又具有碱性易裂解。此外,这些单体可以在可聚合基团和桥头碳之外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,而不会破坏单体。本发明的聚合物和共聚物可降解,但其玻璃转变温度为100°C或更高。
