    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.

    摘要: New 3,5-dialkyl-4-hydroxybenzyl-oxiranes and the corresponding thiiranes are used as stabilizers for polymers. The oxiranes are prepared from the corresponding olefins by reaction with percarboxylic acids or from alkali phenoxides and epichlorohydrines. The thiiranes are prepared from the oxiranes by the usual sulfidation methods.
