摘要： A water dispersible polyurethane dispersion suitable for use as a curable film-forming composition is provided wherein the dispersion comprises, in water, the reaction product of (i) an acrylic polyol having hydrophilic groups, (ii) a polyol hydrosilylation reaction product of an alkylpolysiloxane and an unsaturated hydroxyalkyl compound, and (iii) a polyisocyanate component. Preferably, the acrylic polyol comprises a copolymer containing aromatic groups and having a glass transition temperature of at least about 0° C.

摘要： A linear polymer has repeating units represented by the formula wherein (a) n is an integer greater than or equal to 0, (b) x is an integer greater than or equal to 1, and  represents an unconjugated acetylenic group when x is equal to 1 or conjugated acetylenic groups when x is greater than 1; (c) Ar is an aromatic group, and (c) R1, R2, R3, R4, R5, R6, R7 and R8 are independently selected from the group consisting of alkyl, aryl, alkylaryl, haloalkyl, haloaryl and mixtures thereof. The linear polymer may be thermally cured to form a crosslinked polymer.
