Abstract: Curable compositions containing a compound comprising a conjugated diene group and a 1,1-di-activated vinyl compound are described. The curable compositions can cure by pericyclic reaction mechanisms.

Abstract: Tin-containing catalysts are provided comprising a compound of formula I. I: L1, L2, L3, and L4 are each independently selected from —O—, —S—, —OC(?O)—, —OC(?S)—, —SC(?O)—, —SC(?S)—, —OS(?O)2O—, —OS(?O)2— —N(R6)-, and —OP(?O)(R6)-, wherein R6 represents hydrogen or a monovalent aliphatic, araliphatic, cycloaliphatic or aromatic group having up to 20 carbon atoms. R1, R2, R3, R1?, R2?, and R3? each independently represent a divalent aliphatic, araliphatic, cycloaliphatic or aromatic group having up to 20 carbon atoms; and R4, R5, R4?, and R5? each independently represent hydrogen or a monovalent residue derived from reaction of a respective N—H group with an isocyanate, an ethylenically unsaturated compound, a lactone, a dilactone, a thiolactone, a lactam, a thiolactam, a carboxylic acid or derivative thereof, or an epoxide. Also provided are curable compositions containing these catalysts and methods of controlling the rate of cure of curable compositions.

Abstract: Disclosed is a coating composition comprising a resinous binder prepared from a reaction mixture comprising (a) a first component; (b) a second component; and (c) a third component comprising a block copolymer having (i) a first block comprising units having functional groups reactive with at least one of the first and second components and (ii) a second block comprising units having functional groups that promote adhesion to a polymeric substrate, provided that the first component, the second component, and the block copolymer differ from each other. The block copolymer may also be used as an additive in a coating composition.
