摘要：

New crosslinked microcrystalline cellulose plastic films were made by olefin metathesis. Cellulose was first acylated under microwave irradiation by 10-undecenoyl chloride in lithium chloride/NN-dimethylacetamide homogeneous solution to yield unsaturated fatty acid cellulose esters with a degree of substitution (DS) varying from 1 to 2. After studying the variation of cellulose DS vs. microwave irradiation time, the unsaturated fatty acid cellulose esters were subjected to olefin metathesis using Grubbs's catalyst. Crosslinking ratio T (0% < T < 90%) and gel formation during cross metathesis of cellulose esters with different DS are discussed. Structure elucidation was mainly achieved from IR and H-1 NMR spectroscopic data.
