A zwitterionic polysiloxane polymer (e.g., a polyurethane elastomer) composition having poly(dialkylsiloxane) blocks and a zwitterionic moiety is prepared by the copolymerization of a poly(dialkylsiloxane) diol, a diisocyanate, a tertiary amine alkyl diol, and a poly(dialkylsiloxane) diamine to form a poly(urethane urea) copolymer. A substituted saturated heterocylic compound is reacted with the tertiary amine of the poly(urethane urea) copolymer to introduce a zwitterionic group into the poly(urethane urea) copolymer backbone. A polysiloxane polymer having a zwitterionic moiety is prepared by reacting a diallyl tertiary amine compound and a substituted saturated heterocylic compound to form a diallyl zwitterionic macromer and cross-linking a vinyl terminated poly(dialkylsiloxane) and the diallyl zwitterionic macromer with a curing agent to introduce a zwitterionic group into the poly(dialkylsiloxane) polymer.
