    Abstract: Preparation of open cell polyurethane foams comprises reacting the following components: (A) (modified) organic di- and/or polyisocyanates; (B) high molecular weight compounds with at least two reactive hydrogen atoms; (C) fatty chemical, cell-opening polyols obtained by the addition of nucleophilic compounds to triglycerides containing epoxy groups; and (D) optional chain extenders and/or cross-linking agents, in the presence of (E) propellants, (F) catalysts and (G) optional additives. Also claimed are (i) foams prepared by this method, and (ii) the use of (C) for the preparation of open cell polyurethane foams.

    Abstract: Elastomers (I) with bound ester and urethane gps. contain on (I) 0.1-10% (all pts.wt.) of at least one phenylenebisoxazoline (II) of formula (A) and/or (B), where R1-R3 (same or different) are H, Ph or 1-5C alkyl. Also claimed is the prepn. of polyurethanes (III) contg. bound ester gps. by reacting (A) organic polyisocyanates with (B) higher molecular at least difunctional, polyesterols and (C) chain lengthening agents and/or crosslinking agents in presence of (D) a (II), opt. in presence of (E) blowing agents, (F) catalysts, (G) auxiliaries and/or additives. USE/ADVANTAGE - Used as moulded articles, partic. in machinery construction and transport industries, esp. as flexible pipes, skins, sheets, spring elements, buffers and top coats; foams in furniture, household appts., shoe and motor car industries, e.g. in seats, insulating or cladding materials, sun blinds, head rests, shoe soles, ski cores and receptacles for skis. (I) and (III) have improved hydrolysis resistance and mechanical properties (partic. tensile strength, extension to break), (II) are soluble in starting materials or can be readily incorporated in (I) granulate, do not affect morphology of (I) or (III) and do not migrate.

    Coupling agent(s) for 2-component polyurethane adhesive(s) - comprise enamine(s), esp. 2-N-morpholinyl-cyclo:hex-1-ene, which are incorporated in poly:ol component

    Abstract: Enamines of formula (I) are useful as coupling agents in 2-component polyurethane (PU) adhesives (II). In (I), R4, R5 = 1-8C alkyl, 7-13C aralkyl or 4-8C cycloalkyl, or the two gps. plus the N atom can form a 5-7 membered heterocycle; CnH2n = 3-12C alkylene with at least 3 directly linked C atoms. Pref. (I) is 1-(N-morpholinyl)-cyclohex-1-ene (IA). USE/ADVANTAGE - Coupling agents for 2-component PU adhesives, which can be incorporated into component 2 (i.e. the active H-contg. component based on polyhydric alcohols, etc.). Prior-art coupling agents are either only suitable for 1-component PU adhesives or have to be mixed with the polyisocyanate (component 1). The use of (I) gives improved adhesion on glass, metal, etc., together with improved mechanical properties.
