    摘要: The present invention relates to aqueous secondary copolymer dispersion comprising a copolymer (P) synthesized from a mixture of free-radically polymerizable monomers (M) comprising: (M1) cycloaliphatic esters of acrylic and/or methylacrylic acid; (M3) hydroxy-functional, free-radically polymerizable monomers; (M4) carboxyl-functional, free-radically polymerizable monomers and (M5) hydroxyl- and carboxyl-free (meth)acrylic esters having C1 to C12 hydrocarbon radicals in the alcohol moiety and/or vinylaromatics, wherein the mixture further comprises polyols (PO) selected from the group of polyester polyols and/or polycarbonate polyols, the polyols having an average hydroxyl group functionality of at least 2. The invention also relates to a method for the production of such a dispersion, to the use of the dispersion as a coating and as a binder in 2K polyurethane coatings.

    摘要: This invention relates to a process for producing natural oil based poly-urethane dispersion, in which the hydrophobic polyol comprising the prepolymer of the dispersion is made using a natural hydroxyl oil, which is converted or modified into pure poly-diols by selective capping or blocking at temperatures of less than 100° C., without using the process of esterification or alcoholysis for deriving such polyol. The resultant dispersion is substantially free of volatile organic chemicals and/or leachable contaminants, and is naturally biodegradable.

    摘要: The present invention relates to novel waterborne adhesives which are polymerizable by UV light and are capable of being activated by heat, and which particularly display good adhesion to difficult substrates, such as ethylene vinyl acetate copolymers (EVA) with a low vinyl acetate content, or rubber. The invention further provides a novel method in which, after the application of the waterborne adhesive to an article and drying, irradiation with UV light and at the same time or thereafter activation by heat are performed. The adhesive film which is irradiated and activated in this way is then bonded to a further article. The invention also provides the use of the adhesives to make items such as shoes.
