Abstract
The present invention relates to a flame retardant which is a graft copolymer. The graft copolymer is obtained by polymerizing a vinyl monomer containing at least two polymerizable groups, and at least one other vinyl monomer, in the presence of polyorganosiloxane particles in a latex state. The polyorganosiloxane particles contain grafting agents that are unevenly distributed on the surface thereof. The present invention also relates to thermoplastic resins containing this flame retardant.
