Abstract
Stable, aqueous emulsion copolymers with controllable siloxane crosslinking functionality are provided. These copolymers are prepared by a concurrent free radical and cationic initiated emulsion polymerization of at least one free radical initiatable monomer at least one linear siloxane precursor monomer, and at least one bifunctional silane monomer having both free radical polymerizable and silicon functional groups. The copolymers are useful in curable coatings, paints, caulks, adhesives, non-woven and ceramic compositions and as modifiers, processing aids and additives in thermoplastics, cements and asphalts.
