    摘要： The invention relates to polysiloxane graft polymers composed of a silicone core a) that is surrounded by one or several polymer shells b) and contains one or several optional inner cores c) which are surrounded by the silicone moiety a). The silicone moiety a) contains a1) one or several structural units from the group comprising the general formula [R12SiO2/2], a2) one or several structural units from the group comprising the general formulas [R11-xR2x+1SiOR12/2], [R2SiO3/2], and [R12-yR2y+1SiO1/2], and a3) one or several structural units with ethylenically unsaturated groups or mercaptoalkyl groups of general formula [R3aR4bSiOz/2], and, optionally, a4) one or several trifunctional and tetrafunctional structural units of general formulas [R1SiO3/2} and [SiO4/2]. The polymer shell b) represents a polymer of one or several monomers from the group comprising ethylenically unsaturated monomers while the inner core c) represents a polymer of one or several monomers from the group comprising ethylenically unsaturated monomers. In said formulas, R1 represents identical or different, optionally substituted alkyl radicals with 1 to 18 C atoms, R2 represents identical or different radicals with conjugated electron pairs, R3 represents identical or different radicals of formulas -(CH2)m-CR5=CH2, -(CH2)m+1-O(C=O)-CR5=CH2, and -(CH2)m+1-SH, R4 has the meaning of R1 or R2, R5 represents H or CH3, and a = 0 to (4-z), b = 0 to (3-z), m = 0 to 6, x = 0 or 1, y = 0 to 2, and z = 1 to 3.
