Crosslinked aminosilicone polymer and methods for its preparation and use

A crosslinked aminosilicone polymer comprising average unit formula:

• each R is an independently selected monovalent hydrocarbon group of 1 to 6 carbon atoms;
• each L1 is an independently selected linking moiety, where L1 bonds with D7;
• each L2 is an independently selected linking moiety, where L2 bonds with D4;
• each D1 is an independently selected divalent hydrocarbon group of 2 or more carbon atoms;
• each D2 is an independently selected divalent hydrocarbon group of 1 or more carbon atoms;
• each D3 is independently selected from a covalent bond or a divalent hydrocarbon group of 1 or more carbon atoms;
• each D4 is an independently selected divalent hydrocarbon group of 2 or more carbon atoms, an aminofunctional alkylene group of 2 or more carbon atoms, or a group which is a reaction product of NH reacting with an epoxy functionality;
• each R1 is independently a hydrogen atom or a covalent bond linking to D8;
• each D5 is an independently selected divalent hydrocarbon group of 1 or more carbon atoms;
• each D6 is an independently selected a divalent hydrocarbon group of 2 or more carbon atoms.
• D7 is an oxygen atom when subscript x>0, and D7 is absent when x=0;
• each subscript x is independently 0, 1, or 2;
• each D8 is a divalent hydrocarbon group of 1 or more carbon atoms;
• subscript a is 1 or more;
• subscript b is 1 or more;
• subscript c is 2 or more;
• subscript d is 0 or more;
• subscript e is 0 or more;
• a quantity (c+d+e) is up to 2000;
• with the proviso that subscripts a and b and group D4 are selected such that the crosslinked aminosilicone polymer has >0 to 10% amine content.
