Abstract: The present disclosure relates to compositions comprising a copolymer derived from polymerizing monomers comprising a vinyl aromatic monomer, butadiene, and an acid monomer, in the presence of a chain transfer agent. The chain transfer agent can be present in an amount sufficient to reduce the theoretical glass transition temperature (Tg) of the copolymer by at least 5° C. compared to a copolymer polymerized using identical monomers in the absence of the chain transfer agent. The compositions can be used to prepare compositions such as coatings that have improved water resistance. Methods of making the copolymers are also provided.

Abstract: Described herein are methods of making a composition, the method comprising polymerizing monomers comprising a hydrophobic monomer in the presence of a solid grade oligomer, thereby forming a (co)polymer derived from the hydrophobic monomer, wherein the (co)polymer is derived from 5% by weight to 100% by weight of the hydrophobic monomer based on the total monomer weight. The hydrophobic monomer has a solubility in water of 0.2 g/100 g or less as measured at 20° C. The hydrophobic monomer comprises a substituted or unsubstituted C10-C22 alkyl (meth)acrylate, a substituted or unsubstituted C8-C20 alkenyl (meth)acrylate, a substituted or unsubstituted C5-C12 cycloalkyl (meth)acrylate, or a combination thereof. In some examples, the hydrophobic monomer can comprise lauryl (meth)acrylate, stearyl (meth)acrylate, heptadecyl (meth)acrylate, linoleyl (meth)acrylate, behenyl acrylate, cyclohexyl (meth)acrylate, isodecyl (meth)acrylate), nonyl (meth)acrylate, tridecyl (meth)acrylate, pentadecyl (meth)acrylate, 3-methylbut-2-enyl methacrylate, 3,7-dimethylocta-2,6-dienyl (meth)acrylate, or a combination thereof.
