摘要
Abstract
The structure of aqueous dispersion of ethyl acrylate-methyl methacrylate copolymer(hereinafter referred to as copolymer aqueous dispersion)was explored.The structures of ethyl acrylate,methyl methacrylate,water,and copolymer aqueous dispersions were studied using mid infrared(MIR)spectroscopy.The infrared absorption modes of the molecular s tructure of ethyl acrylate include νasC-H(RCH=CH2)-ethyl acrylate,νsCH3-ethyl acrylate、νsCH2-ethyl acrylate、νC=O-ethyl acrylate、νC=C(RCH=CH2)-ethyl acrylate、νasC-O-C-ethyl acrylate,νsC-O-C-ethyl acrylate and δCH2-ethyl acrylate.The infrared absorption modes of the molecular structure of methyl methacrylate includeνasC-H(R1R2C=CH2)-methyl methacrylate,νasCH3-methyl methacrylate,νasCH2-methyl methacrylate,νsCH2-methyl methacrylate,νC=O-methyl methacrylate,νC=C(R1R2C=CH2)-methyl methacrylate,δasCH3-methyl methacrylate,δsCH3-methyl methacrylate,andνsC-O-C-methyl methacrylate.The infrared absorption modes of water molecule structures include:νH2O-water and δH2O-water.The infrared absorption modes of copolymer water dispersion structures include νH2O-copolymer water dispersion,νC=O-copolymer water dispersion,,νC=C-copolymer water dispersion/δH2O-copolymer water dispersion,νasC-O-C-copolymer water dispersion and νsC-O-C-copolymer water dispersion.MIR spectroscopy can quickly investigate the structure of copolymer water dispersions.关键词
