    Abstract: 1,222,003. Polymer-based coating and bonding agents. BA DISCHE ANILIN- & SODAFABRIK A.G, 25 June, 1968 [28 June, 1967], No. 30260/68. Heading C3P. [Also in Division B2] Coating or bonding agents comprise a copolymer of (a) 10-95% by weight of an acetoacetate of the formula where Y is a C 2 -C 10 divalent hydrocarbon radical and R is H or methyl, (b) 5-90% by weight of an acrylic and/or methacrylic ester of a C 1 -C 20 alkanol and/or styrene and (c) 0-30% by weight of one or more other comonomers; together with an acetylacetonate of a polyvalent metal and a liquid diluent. The optional comonomer(s) (c) may be selected from vinyl carboxylate esters, N-methylol-(meth)- acrylamide and ethers thereof, acrylic and methacrylic acids and salts, amides, nitriles and hydroxyalkyl and dimethylaminoethyl (HCl salt form) esters thereof, and vinyl and vinylidene halides. The hetal component of the acetylacetonate may be Al, Zn, Ni, Be, Mg, Zr, Ti, Co or Cu. Suitable liquid diluents include aromatic hydrocarbons, aliphatic ketones and esters, glycol esters or ethers, essential oils, glycol, alkanols, tetrahydrofuran and water. The agents may optionally include components such as plasticizers, pigments, flow improvers, phenoplast resins, aminoplast resins, phthalate resins, oil-modified phthalate resins, alkyd resins, epoxy resins, other acrylate resins, cellulose derivatives and colophony. The agents can be applied to a substrate and dried or baked to form clear, hard films; hardening may be accelerated by the presence of a compound of Fe, Co, Pb or Mn. The agents are also useful in bonding textiles and non-woven fabrics, and for laminating.

    Abstract: The invention relates to a process for preparing high temperature-resistant dense or cellular polyurethane elastomers by reacting the following, preferably using low-pressure processing techniques: (a) organic polyisocyanates, preferably in the form of isocyanate group-containing prepolymers and/or modified urethane group-containing organic polyisocyanates, with (b) relatively high molecular weight compounds having at least 2 reactive hydrogen atoms, (c) urea derivatives and, optionally, (d) chain extenders and/or cross-linking agents in the presence of (e) catalysts and, optionally, (f) blowing agents (g) auxiliaries and/or additives wherein amino and/or hydroxyl group-substituted ureas and/or polyureas having molecular weights from 200 to 4000 are also used as the urea derivatives. Said ureas and/or polyureas are prepared by reacting organic diisocyanates with primary aliphatic and/or cycloaliphatic diamines and/or alkanolamines in molar ratios of from 1:1.1 to 1:2, preferably in the presence of polyester or polyether polyols as solvents or diluting agents.
