Sythesis and Characterization of Acrylate Monomer Derived from Tannins Model Compound
摘要
Abstract
Methyl gallate acrylate ( MG-AC) was prepared by reaction between methyl gallate ( MG) ( tannins model compound) and acryloyl chloride (AC).The effects of temperature and raw materials molar ratio on the yield of product were investigated.FT-IR,GC-MS,elemental analysis,13C NMR and GPC were used to characterize its structure and polymerization activity.And then,the optimum synthesis conditions were 35℃, molar ratio of AC and MG 1. 1∶1. Under these conditions, the yield of product was 83.9%.FT-IR results showed that the acrylate-functional-group was successfully grafted onto methyl gallate.GC-MS results showed that the purity of methyl gallate acrylate was 98.86%.Elemental analysis indicated that the mass fractions of carbon,hydrogen and oxygen were 55. 46%, 4. 20% and 40. 33%, respectively. They almost agreed to the theoretical value of MG-AC. Thus, the synthesized MG-AC was monosubsituted monomer.13C NMR results comfirmed the monosubsituted structure of monomer. GPC analysis results showed that the MG-AC could polymerize in the presence of the initiator,and the Mw,Mn and Mw/Mn of the polymer were 13 637,11 820 and 1.15.All the results showed that the methyl gallate acrylate was successfully synthesized and had good polymerization activity.关键词
