    摘要: A process for making integral skin foams which comprises reacting into a closed mould :

    A) an organic polyisocyanate
    B) an isocyanate-reactive composition comprising :

    (i) a catalytically effective amount of a urethane-­promoting catalyst and optionally a urea-promoting catalyst,
    (ii) a catalytically effective amount of a carbodiimide-­promoting catalyst, and
    (iii) an isocyanate-reactive compound; in the presence of

    C) an inert physical blowing agent.

    The process provides integral skin foams having good skin properties at reduced physical blowing agent levels.

    摘要: A process for preparing polymeric foams which comprises reacting :
    a) an organic polyisocyanate b) an isocyanate-reactive composition comprising :
    i) an organic polyfunctional isocyanate reactive composition comprising at least 50% w of polyfunctional isocyanate reactive compounds having a molecular weight of above 1500 wherein at least 25% of the isocyanate reactive groups are imino or enamino groups, and at most 50% by weight of polyfunctional isocyanate reactive compounds having a molecular weight of 60-1500, and ii) a catalytically effective amount of a carbodiimide promoting catalyst, and iii) optionally other catalysts and/or further conventional additives, in the substantial absence of water and chlorofluorocarbon blowing agent.
