摘要:
Liquid stoving-lacquer systems based on oil-free polyesters obtained by reacting polybasic carboxylic acids or their anhydrides and 2-ethylpropane diol-1.3 and optionally additional polyhydric alcohols, are highly compatible with melamine resins.
摘要:
Diphenylamine is made by heating aniline under pressure and temperatures of 250.degree.-400.degree. C in the presence of a boron/fluorine compound and water.
摘要:
Unsaturated polyester resins which are suitable for the production of cross-linked polyesters which are with difficulty to saponify contain, in part at least, radicals of 2-alkyl-1.3-propane diols as the alcohol component.
