    • Disclosed herein are compounds of the structure wherein R1, R2, and R3 are organic radicals of C1 to C20, such that the combination of the three contain at least twelve carbon atoms and R3 is bound to the methylene carbon atom between X and the aromatic ring by at least one saturated carbon atom, allowing it to be easily separated from the polymerizable monomer by distillation; R1 and R2 have sufficient steric bulk to protect the phenol from reacting with an alkoxy group or halogen bound to silicon; and X is a neutral heteroatomic radical of oxygen, nitrogen, or phosphorus; and their use as inhibitors for the polymerization of (meth)acryloxysilanes.
    • 本文公开的是其中R1,R2和R3是C1至C20的有机基团的结构的化合物,使得三者的组合含有至少十二个碳原子,并且R 3通过在X和芳环之间与X和芳环之间的亚甲基碳原子结合 至少一个饱和碳原子,允许其通过蒸馏容易地与可聚合单体分离; R1和R2具有足够的空间体积以保护苯酚与与硅结合的烷氧基或卤素反应; X是氧,氮或磷的中性杂原子; 以及它们作为(甲基)丙烯酰氧基硅烷聚合抑制剂的用途。
