Disclosed herein are compounds of the structure
1
wherein
R
1
, R
2
, and R
3
are organic radicals of C
1
to C
20
, such that the combination of the three contain at least twelve carbon atoms and R
3
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;
R
1
and R
2
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.
本文公开了结构1的化合物,其中R1、R2和R3是C1到C20的有机基团,三者的组合至少包含十二个碳原子,并且R3通过至少一个饱和碳原子与X和芳香环之间的亚甲基碳原子结合,从而可以通过蒸馏轻松地与聚合单体分离;R1和R2具有足够的立体阻碍作用,以保护苯酚不与硅键结合的烷氧基或卤素反应;X是氧、氮或磷的中性杂原子基团;以及它们作为(meth)acryloxilanes聚合抑制剂的应用。
