Film obtained from silsesquioxane polymer and method of preparing same

摘要

A film obtained by heating a coating of a resin composition at a temperature lower than 300 DEG C but not lower than 40 DEG C in air or in an inert atmosphere. The resin composition includes a hydrosilylated polymer obtained by reacting at least one hydridosilsesquioxane compound of the following formula (1) : (HSiO3/2)n wherein n is an integer of 4-1000, with at least one compound of the following formula (2) R<1> - C IDENTICAL C - R<2> wherein R<1> represents a hydrogen atom, a monovalent organic group or a monovalent organosilicon group and R<2> represents a hydrogen atom or a group of the formula: - (R')q - C IDENTICAL C - R where R' represents a divalent organic group or a divalent organometallic group, R represents a monovalent organic group or a monovalent organosilicon group and q is 0 or 1 with the proviso that when R<1> is a hydrogen atom R<2> is a hydrogen atom.
