y
-A-(B-A)
x
-B-A-B
y
—Z, where the A monomers units are derived from a diester or diacid, the B monomer units are derived from a difunctional monomer having functional groups co-reactive with the acid or ester groups of the A monomer, x+y is zero to 60, Z comprises an ethylenically unsaturated, polymerizable group, A monomers comprise a 1-methylene-3,3-dimethylpropyl group, and at least one B monomer unit comprises a high refractive index group.
一般公式为Z-By-A-(B-A)x-B-A-By-Z的加成-断裂寡聚体,其中A单体单元来源于二酯或二酸,B单体单元来源于具有与A单体的酸或酯基反应的官能团的双官能单体,x+y为0至60,Z包括一个具有乙烯基不饱和度、可聚合的基团,A单体包括1-亚甲基-3,3-二甲基丙基基团,并且至少一个B单体单元包括高折射率基团。
