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, REquivalent, 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 (REquivalent)2×
