Results indicate that as the molecular mass of polyethylene glycol increases, the conductance is increased obviously, and the surface tension is decreased from 36.28 mN/m to 31.30 mN/m, while the cloud point is increased from 39.6 ℃ to 58.9 ℃. Their emulsifying abilities to BA, MMA and BMA are superior to that of OP-10, and the surfactants is homopolymerize or copolymerize with acrylate at 70 ℃ under the initiation of AIBN.

结果表明，随聚乙烯醇分子量的增加，非离子表面活性剂的电导率显著增加、表面张力由36.28 mN/m降低至31.30 mN/m、浊点由39.6 ℃增加至58.9 ℃，对丙烯酸丁酯、甲基丙烯酸甲酯和甲基丙烯酸丁酯的乳化能力均优于常用乳化剂OP-10，以AIBN作引发剂在70 ℃下既能均聚又可与丙烯酸酯进行共聚反应。

This product is made from amylaceum, a derivant of starch and natural aliphatic alcohol. Except for possessing the outstanding features of traditional surface active agent, the product is also characterized of nontoxic , non-irritative to skin and eye, easy to biodegradation and so on. It's a kind of nontoxic and environmental protection living up to the requirements of human safety and environmental protection.
