BINDER COMPOSITIONS AND METHODS OF PREPARING AND USING THE SAME
This abstract first appeared for US patent application 18958283 titled 'BINDER COMPOSITIONS AND METHODS OF PREPARING AND USING THE SAME
Original Abstract Submitted
The present disclosure relates to compositions comprising a copolymer derived from a vinyl aromatic monomer, a (meth)acrylate monomer, an acid monomer, and a copolymerizable surfactant and compositions comprising the same. The (meth)acrylate monomer can be selected from a monomer having a theoretical glass transition temperature (T) for its corresponding homopolymer of 0° C. or less or a hydrophobic (meth)acrylate monomer. In some embodiments, the copolymer is further derived from an organosilane. The copolymers can have a theoretical glass transition temperature (T) from −60° C. to 80° C. and a number average particle size of 250 nm or less. The compositions can be used to prepare compositions such as coatings that have improved water resistance, blush resistance, and/or resistance to hydrostatic pressures. Methods of making the copolymers are also provided.
