摘　　要：以新型环保型APG 0810(烷基葡萄糖苷)乳化剂作为传统有毒APEO(烷基酚聚氧乙烯醚)乳化剂的替代品,采用预乳化-种子乳液聚合法制备了纯丙烯酸酯聚合物乳液。考察了APG 0810含量和聚合温度对预乳液稳定性、乳液黏度和冻融稳定性、胶膜表面性能和力学性能等影响。结果表明:当w(APG0810)=0.8%～1.5%(相对于乳液总质量而言)时,预乳液的储存稳定时间超过240 min;当w(APG 0810)=1.0%、聚合温度为88℃时,乳液黏度和冻融稳定性明显提高,胶膜综合性能相对最好。With the new envinmmeni-fliendly APG 0810（alkyl glucoshle） emulsifier as subslihlh of hadilinal and loxic APEO（alkylphenol elhxylaie） emulsifier, a pure acrylale polymer emlprepared hy preemulifyin seed-emulsion polymerizalion. The inlluences of APG 0810 ecmlenis and polymerizalion temperalllres on some propertie pre-fmulsion stabilily, visrsily and freeze-thawing tahility of emttlsion, surfare l）roperlie and mechanical roferlie of film were investigaled. The result Showed lhal the stable ortge lime of emulsion was more Ihan 240 rain when mass fralion of APC, 0810 was 0.8%-1.5% in lolal emulsion .The vistsilv andcezc-lhawing stability of emulsion were obviouslv increased, and Ihe film had the relatively besl conbliou properly when mass fraetion of A PG 0810 was 1.0%, and polymerization temperalure was 88℃.
