Claim Text:
1. A solution-processable composition for preparing a photopatternable material, the composition comprising: (a) an oligomeric siloxane component, wherein the oligomeric siloxane component comprises, based on its total weight, between about 40% by weight and about 100% by weight one or more cage-structured polyhedral oligomeric silsesquioxanes of the formula: wherein: each R each R q is 8, 10 or 12; and m and n are integers, provided that m+n=q and m is at least 1; (b) a polymerization initiator; (c) one or more thermosettable polymers selected from the group consisting of polyisoprene, isobutylene isoprene rubber, polybutadiene, styrene-butadiene rubber, acrylonitrile butadiene rubber, hydrogenated nitrile rubbers, ethylene propylene copolymer, ethylene propylene diene rubber, polyacrylic rubber, fluorosilicone rubber, and ethylene-vinyl acetate, wherein the one or more thermosettable polymers collectively are present in an amount between about 1% by weight and about 20% by weight based on the total weight of the oligomeric siloxane component; and (d) a solvent; wherein the oligomeric siloxane component is present in an amount between about 40% and about 98% based on 100% by weight solids of the composition.
