摘要:
PROBLEM TO BE SOLVED: To provide a modified phenol resin that has a low molecular weight and small polydispersity (Mw/Mn), and contains added monomers introduced into the resin skeleton, further has narrowed molecular weight distribution by subjecting a phenol resin of middle or high molecular weight to splitting and rearranging reactions.
SOLUTION: To 100 pts.wt. of phenol resin, 50 to 200 pts.wt. of phenol monomers and 0.1 to 10 pts.wt. of a catalyst are added. Then, the mixture is allowed to react with each other at 120 to 200°C under the atmospheric pressure for 1 to 6 hours. Thereby the unreacted phenols are removed and the resultant modified phenol resin not containing unreacted phenols has a narrowed molecular weight distribution with less than 1.8 polydispersity (Mw/Mn).

要解决的问题:为了提供具有低分子量和多分散性(Mw / Mn)小的改性酚醛树脂,并且含有引入到树脂骨架中的添加的单体,通过使酚醛树脂 的中等或高分子量分裂和重排反应。 解决方案:100磅 的酚醛树脂,50〜200重量份 的酚单体和0.1至10重量份 的催化剂。 然后,使混合物在120〜200℃,大气压下反应1〜6小时。 由此除去未反应的酚,所得到的不含未反应酚的改性酚醛树脂的分子量分布变窄,多分散性(Mw / Mn)小于1.8。 版权所有(C)2008,JPO&INPIT
