摘　　要：在改性方案相同前提下,分别在常规加热搅拌和微波加热条件下对橡椀栲胶进行接枝改性。采用红外光谱和凝胶渗透色谱对改性产物进行分子结构和分子量大小及其分布分析与表征;在两种不同加热条件下,对没食子酸进行了改性,并对产物进行了红外光谱和凝胶渗透色谱分析,结果表明:微波加热有助于促进改性产物分子结构的接枝,反应时间短,热能利用和生产效率高,清洁无污染。Independently, volanea extract and gallic acid are modified by thermal heat treatment and microwave irradiation. The modification of all samples is quantified by the products molecular weight, weight-distribution, and molecular structure, by IR and GPC. The results show that microwave heating help to promote grafting in the molecular structure of the modified products. The reaction time and energy consumption of the microwave process is lower.
