Abstract: The composition includes at least 16 percent by weight of an acrylic monomer comprising a cycloalkyl group having up to 12 carbon atoms, an acrylic monomer having a carboxylic acid group, an acrylic monomer having a hydroxyl group, and a compound composed of divalent segments L and at least two X groups. The divalent segments L are represented by formula L. Each segment L is respectively directly bonded to two secondary N atoms, two tertiary N atoms, or a secondary and a tertiary N atom. Each R1 represents an alkylene group having from 1 to 4 carbon atoms, and at least some of the R1 groups are —CH2—CH2—CH2—CH2—. Each X group is independently represented by the formula CH2═C(R)—C(O)—O—V—W—C(O)—. Articles and methods using the composition are also described.

Abstract: The composition includes an acrylic monomer having a carboxylic acid group, an acrylic monomer having a hydroxyl group, at least one of an alkyl acrylate or alkyl methacrylate, and from 20 to 35 percent by weight of a compound composed of divalent segments L and at least two X groups. The divalent segments L are represented by formula L. Each segment L is respectively directly bonded to two secondary N atoms, two tertiary N atoms, or a secondary and a tertiary N atom. Each R1 represents an alkylene group having from 1 to 4 carbon atoms, and at least some of the R1 groups are —CH2—CH2—CH2—CH2—. Each X group is independently represented by the formula CH2═C(R)—C(O)—O—V—W—C(O)—. The acrylic monomer having a carboxylic acid group is present in an amount of at least one percent and less than 20 percent by weight. Articles and methods using the composition are also described.

Abstract: Provided are novel crosslinkers and curable compositions including such crosslinkers. Bonded constructions including the disclosed curable compositions display high adhesion, elongation, and impact resistance even if the bonded substrate receives no surface treatment prior to bonding. Provided are elastomeric products including the curable compositions, methods of making the same, and uses thereof.
