    Abstract: Hybrid moisture curable compositions comprising an acrylic copolymer, a functional silicone, a crosslinker, and a moisture cure catalyst are disclosed. The acrylic copolymer includes (i) a functional monomer selected from a silane monomer, a siloxane monomer, a hydroxy functional monomer, or a combination thereof or (ii) a reaction product of an amino silane and an acrylic polymer derived from one or more (meth)acrylates and one or more carboxylic acid anhydrides. The hybrid compositions are stable and exhibit properties typically ascribed to each individual polymer component. Methods of making and using the hybrid curable compositions are also described.

    Abstract: The present invention relates to aqueous acrylic polymer latexes, which are suitable as binders in coating compositions for providing flexible roofing. The present invention also relates to coating compositions containing such binders, which are suitable for providing flexible roofing. The aqueous acrylic polymer latexes have a glass transition temperature Tg of at most from −10° C., in particular at most −20° C., or, in case of a multi-stage polymer latex a weight average glass transition temperature Tg of at most from −10° C., where the polymer of the acrylic polymer latex has a carbon polymer backbone formed by polymerized ethylenically unsaturated e monomers M comprising acrylic monomers, and where the carbon polymer backbone bears functional groups of the formula (I) attached to carbon atoms of the polymer backbone *—C(═O)—O—[A-NH]nH (I) where the asterisk indicates the atom attached to a carbon atom of the polymer backbone, n is an integer, the number average of n in all functional groups of the formula (I) being >1, in particular at least 1.1 or at least 1.2 or at least 1.3, and A is selected from the group consisting of 1,2-ethandiyl or 1,2-propandiyl, where the functional groups of the formula (I) contribute to the total weight of the polymer in the acrylic polymer latex by 0.1 to 10% by weight.

    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.

    Abstract: Compositions comprising a copolymer, an inorganic filler, and a moisture cure catalyst are described herein. In some instances, the copolymer can be derived from a (meth)acrylate, a carboxylic acid anhydride, and an aminosilane, wherein the aminosilane can be pendant from the copolymer backbone. In other instances, the copolymer can be derived from a (meth)acrylate and an organosilane in the absence of a chain transfer agent at a temperature of at least 150° C. Methods of making and using the compositions are further described. In some examples, the compositions are adhesive compositions and can be used in adhering two substrates, such as in floor covering.
