Process for producing a siloxane copolymer, and a resin composition comprising a siloxane-based copolymer obtained by the production process

摘要

The present invention reacts with siloxane to react with at least one diol as a copolymerization component, at least one dicarbonate, and at least one silicon compound represented by the following formula in the presence of an esterification or transesterification catalyst Manufacturing method of base copolymer:Where R1, R2, R3, and R4 are independently of the hydrogen atom or substituted or unsubstituted organic groups; X and y are independently hydrogen atoms, or substituted or unsubstituted organic groups; a represents an integer of 0 to Indicates an integer between 3 and 20.
