The present invention relates to a method of synthesizing glycidyl ether compounds without the addition of solvent. In particular, the present invention provides the improved preparation of the glycidyl ethers by using fatty alcohols with epichlorohydrin in the presence of alkali metal hydroxide and phase-transfer catalysts in the appropriate molar ratios of them without water and organic solvents.

The invention relates to a process for preparing a stabilized suspen-sion/emulsion polymer of halogen-containing monomers with addition of a polymer stabilizer mixture compatible with the polymerization medium prior to, during or directly after the polymerization process, and to the polymers pre-pared by this process.
Disclosed are stabilizer mixtures comprising at least a) one alkanolamine or one reaction product of a monofunctional or polyfunctional epoxide and ammonia or a monofunctional or polyfunctional dialkyl(aryl)amine or monoalkyl(aryl)amine, and b) one uracil or one initial product and an optional perchlorate salt
所公开的稳定剂混合物至少包含 a) 一种烷醇胺或一种单官能团或多官能团环氧化物与氨或一种单官能团或多官能团二烷基(芳基)胺或单烷基(芳基)胺的反应产物,以及 b) 一种尿嘧啶或一种初始产物和一种任选的高氯酸盐
