Synthesis and Characterization of the Polymer of Rosin Allyl Alcohol Ester and Its Oxide (Ⅱ)——Study on synthesis of the oxide of macroporous reticular polymer of rosin allyl alcohol ester

摘要: 以歧化松香胺席夫碱铜催化剂,H2O2(30%)氧化聚松香丙烯醇酯(PRAAE),得到聚松香丙烯醇酯氧化物.对聚合物进行了红外、紫外、软化点和热失重分析,BET法测定聚松香丙烯醇酯氧化物的微孔大部分分布在nm以上;对聚松香丙烯醇酯氧化物相对分子质量进行了分析,其量在25266以上.结果表明所合成的聚松香丙烯醇酯氧化物为大孔聚合物.

Abstract: Polymer of rosin allyl alcohol ester (PRAAE) was oxidized to produce its oxide through catalysis of disproportionated rosin amine Schiff's base copper salt, and hydrogen peroxide (30%) as oxidant. The polymer was characterized by IR, UV, softening point and TG analysis. Most of micropore sizes of synthesized polymer were above 5 nm, as measured by BET method. It was confirmed that relative molecular weight (Mr) of oxide of rosin allyl alcohol ester was above 25 266. Results showed that the synthesized polymer was a macroporous functional polymer.
