Polyorganosiloxanes and Resin Compositions

Abstract

This invention relates to a polyorganosiloxane having the structure represented by the following formula (1). (In formula (1), R is independently substituted by substituent A or is a monovalent saturated hydrocarbon group having 1 to 4 carbon atoms, at least one of R is substituted by substituent A, and R' is a monovalent organic group having an aliphatic unsaturated bond. Substituent A is a monovalent organic group having 3 to 6 conjugated aromatic six-membered rings, l is an integer of 1 or more, and m and n are integers of 0 or more. Also, in formula (1), the number of aliphatic unsaturated bonds is 2 or more.) none
