Abstract

Provided is a polyorganosiloxane-containing polymer which makes it possible to obtain a molded product exhibiting excellent flame retardance without significantly degrading the impact resistance characteristics in a case where the polyorganosiloxane-containing polymer is added to a resin. The polyorganosiloxane-containing polymer according to the present invention contains alkali metal atoms of 100 ppm by mass or more and has a mass average particle diameter Dw of 350 nm or more.

Claims12

Dependent claims

A polyorganosiloxane-containing polymer comprising:

100 ppm by mass or more of an alkali metal atom,
wherein a mass average particle diameter Dw is 350 nm or more.

Dependencies are inferred from the claim text.
