Title:
BINDER COMPOSITIONS AND METHODS OF PREPARING AND USING THE SAME
Document Type and Number:
WIPO Patent Application WO/2018/098127
Kind Code:
A3
Abstract:
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 (Tg) 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 (Tg) 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.
