Title:
【発明の名称】ポリウレタン分散物
Document Type and Number:
Japanese Patent JP3334908
Kind Code:
B2
Abstract:
Polyurethane dispersions (I) are obtd. by radical polymerisation of polyurethane macromonomers (II) contg. COOH, PO3H or SO3H gps. (gps. X), lateral vinyl gps. and opt. terminal vinyl, OH, urethane thiourethane and/or urea gps.. More specifically (II) are obtd. (a) by polyaddition of polyhydroxy-polyethers, -polyesters or -polycarbonates, and polyhydroxycarboxylic acids, dihyroxyphosphonic acids or polyhyroxysulphonic acids and polyisocyanates, and monomers with at least 2 OH and at least one vinyl gp., to give (II) contg. gps. (X), OH gps. and lateral vinyl gps.; or (b) to give (II) contg. gps. (X), NCO gps. and lateral vinyl gps. (followed by reaction of the latter with amines, alcohols or thioalcohols); or (c) by reaction of the same starting materials followed by reaction with a monomer which contains a vinyl gp. and a gp. which reacts with NCO gps., together with prim. or sec. amines, alcohols or thioalcohols; or (d) by reaction of the same cpds. to give (II) contg. NCO gps. and lateral vinyl gps., followed by reaction with amino- or hydroxy-carboxylic or -sulphonic acids; the polyhydroxy-polyethers, -polyesters or -polycarbonates contain COOH, PO3H or SO3H gps. (X); radical polymerisation is carried out in an unsatd. comonomer (III) which serves as solvent, opt. in the presence of other unsatd. comonomers, or in a mixt. of water and inert solvent (w.r.t. NCO gps.), opt. in the presence of unsatd. comonomers, opt. with distn. of the solvent before or after polymerisation.
