College of Science, Nanjing University of T echnology, Nanjing 210009; 2.Academic Affairs, Lianyungang Technical College, Lianyungang 222006) Abstract Poly(methylsiloxane) modified by polyether, w hich combines the propertied of poly( methylsiloxane) and polyether, w as prepared from polyether and poly(methylsiloxane) . The product structure w as characterized by IR spec trum. Viscosity index, viscositytemperature coefficient and surface t ension of the product w ere tested. The influence of viscosity and hydrogen content of poly( methylsiloxane) on t he propert ies of product w as discussed. According t o unit rat io and polymerization degree of products, the influence of product structure on viscosity index and surface tension w as stud ied. The results indicat ed that in the range of researching, viscosity index and surface tension of product were increasing with the increase of
