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: A description is given of a method of making film laminates using a lamination adhesive comprising (a) at least one acrylic polymer A with anhydride groups which are reactive with primary or secondary amine groups; and (b) at least one compound B with at least two amine groups selected from primary and secondary amine groups. The acrylic polymer A has a molecular weight of from 3000 to 50000 and the lamination adhesive is free of organic solvents, free of water and free of compounds with isocyanate groups.

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.
