    摘要： Spherically polymerized polyolefins can be advantageously stabilized by being treated with at least one emulsion or dispersion containing a stabilizer or a mixture of stabilizers and an amine of formula I ##STR1## wherein R.sub.1 is C.sub.1 -C.sub.20 alkyl which may be substituted by --OH, or is C.sub.3 -C.sub.50 alkyl which is interrupted by one or more oxygen atoms, or is C.sub.1 -C.sub.8 alkoxy, and each of R.sub.2 and R.sub.3 independently of the other is hydrogen or has one of the meanings indicated for R.sub.1, or R.sub.2 and Rphd 3, together with the nitrogen atom to which they are attached, form a 5- to 7-membered heterocyclic ring.

    摘要： The invention relates to a process for the manufacture of foams by warming the mixture to be foamed in the presence of an organic sulphohydrazide, an organic compound which contains amide groups and a salt of a metal of group IIa or IIb of the Periodic Table. Integral or non-integral foams having a uniform and fine pore structure are obtained.

    摘要： According to the invention, polyaddition products containing imide groups are manufactured by reacting certain polyimides (preferably maleimides) with polycarboxylic acids in the presence of basic compounds. The preferred embodiment (C) relates to the use of catalysts as basic compounds. In particular, tertiary amines, secondary amines or mixed tertiary-secondary amines can be used. A further embodiment (D) relates to the use of primary polyamines as basic compounds. In the latter case, the polyamine participates in the polyaddition mechanism, that is to say the molecules are incorporated into the polyaddition products. In this latter case, catalysts can also be used additionally.The invention can be utilized particularly in the fields of surface protection, the electrical industry, laminating processes, and the manufacture of foamed plastics, and in the building industry.

    摘要： Epoxide resin foams are manufactured by curing a mixture which contains an epoxide resin, a blowing agent, a surface-active agent and the tetraglycidyl ester of cyclohexanone- or methylcyclohexanone-2,2,6,6-tetrapropionic acid, with a Lewis acid or an addition compound or complex compound of a Lewis acid. The foams obtained show a homogeneous pore structure and no tendency to crack formation, and are heat-stable and largely light-fast. They can be employed in sandwich constructions, as insulating materials against heat and cold, sound and mechanical impact, and in the electrical industry.
