ZWITTERIONIC SILOXANE POLYMERS AND IONICALLY CROSS-LINKED POLYMERS FORMED THEREFROM

摘要

Ionically cross-linked silicone polymers of a thickened gel-like consistency are made by reacting a diamino containing polysiloxane with an acid containi ng reactant selected from itaconic acid or the ester derivative thereof; substituted or unsubstituted cyclic and ankydride; substituted or unsubstituted conjugated olefinic acid or mixtures of the same at an elevate d temperature in the presence of a low molecular weight silicone oil or other solvent until an ionically cross-linked zwitterionic siloxane polymer of a g el- like consistency is formed.
