Abstract
A composition includes a siloxane of the formula:
wherein a is at least 2, b is from 3 to 20, c is from 0 to 10, d is from 0 to 10, and each R is independently of the formula —CR′2—CR′2—Y—Z or CR′2—CR′2—Z, wherein each R′ is independently a hydrogen atom or a C1 to C10 hydrocarbyl free of aliphatic unsaturation so long as at least one R′ is a hydrogen atom, Y is a divalent organic group, and Z is a polycyclic group containing at least one aromatic ring. A method of making the siloxane includes charging (HMe2SiO1/2)a(MeHSiO2/2)b(HSiO3/2)c(SiO4/2)d, a platinum catalyst, and an alkene of the formula CR′2═CR′—Y—Z or CR′2═CR′—Z into a reactor to form the siloxane.
