The present invention pertains to a composition of matter and to a method of using the composition to produce foamed plastics, wherein a major, auxiliary source of blowing agent for the foam is the decomposition of dialkyl dicarbonates. The dialkyl dicarbonates can be decomposed over temperatures ranging from about 10°C to about 45°C when used in combination with particular tertiary amine decomposition catalysts.
本发明涉及一种物质组合物和使用该组合物生产发泡塑料的方法,其中泡沫塑料发泡剂的主要辅助来源是二烷基二
碳酸盐的分解。当与特定的叔胺分解催化剂结合使用时,二烷基二
碳酸盐可在约 10°C 至约 45°C 的温度范围内分解。
