| Application: |
With vinyl double bond within the molecule it can copolymerize with other monomer to produce copolymers with hydroxy group in the side chain, And these structure are readily undergo across-linking reaction. The most important application of hema is production of coatings It copolymerizes with monomers such as styrene, methyl methacrylate, butyl acrylate and methacrylic acid and etc. Produce coatings and primers for auto applications. Also in applications of uv or eb radiation polymerizations, printing pads, printing oil. gel, contact lens, and hearing aid equipment coatings.
The resinss property can be raised obviously by using a small quantity of this functional monomer. |
