Abstract:
1. A partially ethylenically-functionalized polysiloxane, which is a mixture of reaction products obtained by reacting an ethylenically functionalizing vinylic monomer having a first reactive functional group with a linear functional polysiloxane compound having two terminal second reactive functional groups at a molar equivalent ratio, R Equivalent , of from about 40% to about 97%, wherein each first reactive functional group reacts with one second reactive functional group in the presence or absence of a coupling agent to form a covalent bond or linkage, wherein the mixture of reaction product comprises (R Equivalent ) 2 ×100% by mole of a linear polysiloxane crosslinkers having two terminal ethylenically-unsaturated groups, 2×R Equivalent ×(1−R Equivalent )×100% by mole of a polysiloxane vinylic monomer or macromer having one terminal second reactive functional group and one terminal ethylenically-unsaturated group, and (1−R Equivalent )×(1−R Equivalent )×100% by mole of unreacted linear polysiloxane compound with two terminal second reactive functional groups.
