Several polymers are used for the fabrication of adhesives and coatings. Poly(vinyl acetate) latexes arepolymers that are stable in aqueous dispersion. These polymers are environmentally friendly and exhibitsuperior prospects due to their waterborne nature, having lower volatile organic compounds and betterfilm-forming property. However, the accumulation of static charges on the surface of these polymers is a majorproblem for using them as adhesives or coatings. This is why it is important to determine if the change in theexperimental conditions of the preparation of these polymers can affect their electrostatic properties. Ourshort-term objective is thus to determine the electrostatic properties of several poly(vinyl acetate) latexes inorder to develop novel latexes with appropriate electrostatic properties.

多种聚合物用于制造粘合剂和涂料。聚(乙酸乙烯酯)胶乳是在水分散体中稳定的聚合物。这些聚合物具有水性、挥发性有机化合物含量低、成膜性好等特点，对环境友好，具有良好的前景。然而，这些聚合物表面静电荷的积累是将它们用作粘合剂或涂料的主要问题。这就是为什么确定这些聚合物制备的实验条件的变化是否会影响它们的静电性能很重要。因此，我们的短期目标是确定几种聚（乙酸乙烯酯）乳胶的静电性能，以开发具有适当静电性能的新型乳胶。
