Abstract: Without using any solvent, a maleopimaric acid (MPA)modified methoxy terminated poly dimethylsiloxane )(MP-MOS) was firstly synthesized by the one-pot reaction of MPA, dimethyl dimethoxy silicane (DMDMOS), octamethyl cyclotetrasiloxane(D,),and hydrolyzate of 3-aminopropyl( diethoxy )methylsilane (HAPMS). As a result, MPA based im-ide heterocycle (MPABl) was incorporated into the side chain of polysiloxane. MP-MOS was further characterized by 1H-NMR, 13C-NMR and FT-IR. Without using any heavy metal catalyst, MP-MOS itself could form a coating having mechanical strength by room temperature vulcanization. The results derived from differential scanning calorimetry(DSC)and thermogravimetric analysis(TGA )showed that the curing product from MP-MOS showed excellent high and/ or low temperature resistance.

摘要： 以马来海松酸（MPA）、八甲基环四硅氧烷（D₄ ）、γ－氨丙基甲基二乙氧基硅烷的水解物（HAPMS）和二甲基二甲氧基硅烷（DMDMOS）为原料，在不需要溶剂的条件下，采用一锅法合成了一种侧基含有 MPA 基酰亚胺杂环（MPABI）的甲氧基封端聚硅氧烷树脂（MP-MOS），并利用核磁共振（1H-NMR、13C-NMR）和红外光谱（FT-IR）对其结构进行了表征。 研究发现，MP-MOS 树脂无需催化剂就可室温硫化成具有一定强度的涂膜。 利用热重分析（TGA）和差式扫描量热法（DSC）表征了 MP-MOS 树脂室温固化物，数据表明，其具有耐高低温性能。
