| titleOfInvention | A kind of synthetic method of styrene-dicyclopentadiene monomaleate copolymer |
| abstract | The present invention relates to a kind of styrene-dicyclopentadiene monomaleate copolymer synthetic methods, this method is with dicyclopentadiene and maleic anhydride in xylene solution system, anhydrous sodium acetate catalysis reaction, generate dicyclopentadiene maleic anhydride monoesters, wherein esterification yield is 95%, again using dicyclopentadiene monomaleate and styrene as monomer polymerization, obtain degradation material styrene-dicyclopentadiene monomaleate copolymer, after tested the result shows that: through the invention the method obtain styrene-dicyclopentadiene monomaleate copolymer number-average molecular weight be 45000-65000, molecular weight distribution is 1.1-1.5, molecular weight is larger and molecular weight distribution is relatively narrow.Styrene-dicyclopentadiene monomaleate copolymer is due to having functional double bond, carboxyl and higher biodegradability, it is thus possible to be normally used as a kind of function admirable high molecular material come using.Present invention process cleans, is with high safety, easy to operate, is convenient for large-scale production. |
