  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。

  The reaction of BOC2O in the presence and absence of DMAP was examined with some amines, alcohols, diols, amino alcohols, and aminothiols. Often, unusual products were observed depending on the ratio of reagents, reaction time, polarity of solvent, pK(a) of alcohols, or type of amine (primary or secondary). In reactions of aliphatic alcohols with BOC2O/DMAP, we isolated for the first time carbonic-carbonic anhydride intermediates; this helps explain the formation of symmetrical carbonates in addition to the O-BOC products. In the case of secondary amines, we succeeded to isolate unstable carbamic-carbonic anhydride intermediates that in the presence of DMAP led to the final N-BOC product. The effect of N-methylimidazole in place of DMAP was also examined.

  An object of the present invention is to obtain color filters having a high contrast, a high color purity and an improved transmittance for blue color, and a display using the color filters. In the present invention, there is used a colored composition for color filter comprising at least one coloring agent, a base polymer and at least one solvent, said base polymer containing a polyamicacid whose light transmittance decreases by 2% or less in the visible region (wavelength: 400 nm to 800 nm).
