Abstract: Process for the synthesis of polymers with laterally linked polyoxyalkylene chains by the free radical polymerization of polyoxyalkylene ethers with olefinic double bonds with other vinyl compounds, capable of copolymerizing wherein the polyoxyalkylene ethers of allyl and/or methallyl alcohol are copolymerized in a known manner with vinyl esters of lower carboxylic acids or mixtures of vinyl esters of lower carboxylic acids with up to 50 mole percent of esters of acrylic or methacrylic acid. The compounds can be used to advantage as reaction components having hydroxyl groups in the production of polyurethanes. In particular, they improve the mechanical properties of polyurethane foams, such as, for example, their compression hardness.

Abstract: This invention relates to a thermosetting, substrate-free, storage-resistant synthetic resin foil which is hard, scratch- and abrasion-proof in the hardened state, comprising: (a) about 60 to 95% by weight of a hardenable polyester resin, (b) about 1 to 15% by weight of a cross-linking agent for the polyester resin, (c) about 5 to 40% by weight of a thermoplastic containing predominantly linear, high-molecular weight reactive groups, (d) about 1 to 15% by weight of a monomer with at least one polymerizable double bond and at least one group reactable with the reactive group of the thermoplastic under the conditions of reaction, (e) and at least one hardening catalyst, and optionally dyestuffs, pigments and/or fillers.
