What is the problem of the selection of functional monomers

The conventional styrene-acrylic emulsion is mainly composed of styrene, butyl acrylate and a small amount of acrylic acid. The styrene-acrylic emulsion obtained by polymerizing only three kinds of monomers has many problems, such as poor film forming property, high minimum film forming temperature, low coating strength, water resistance of the coating, erosion resistance, and poor light resistance. In order to impart more excellent properties to the styrene-acrylic emulsion, a small amount of functional monomer may be introduced by blending or copolymerization to effect modification of the styrene-acrylic emulsion.
