Abstract
(EN)
The present invention is a (meth)acrylic graft silicone that is represented by formula (I). (I) M1aM2bD1cD2dT1eT2fQg, wherein M1=R13SiO1/2, M2=R12R2SiO1/2, D1=R12SiO2/2, D2=R1R2SiO2/2, T1=R1SiO3/2, T2=R2SiO3/2, and Q=SiO4/2 (R1 being a hydrogen atom, an alkyl group, or an aryl group, and R2 being a group that has a (meth)acrylic polymer structure that is represented by formula (II) (A being a bivalent organic group, R3 being a hydrogen atom or an alkyl group, R4 being a hydrogen atom or an alkyl group, R5 being a monovalent hydrocarbon group, an amino group, a siloxy group, a halogen atom, or a hydroxyl group, and n being a positive integer), a, b, c, d, e, f, and g being 0 or a positive integer, provided that b+d+f≥1, and the bond order of the siloxane units being arbitrary). The present invention thereby provides a high-purity, highly heat-resistant (meth)acrylic graft silicone.
