The polymers of this G**-containing has excellent heat and chemical resistance , stain resistance , low refractive index, non-cohesiveness, water and oil repellency, electric insulating properties.and etc , because it contains plentiful fluorine in its side chain, the weight ratio of fluorine in its molecular weight is *7% and atom ratio in its molecular is *0%. The tranquilization is better than other monomers. The fluorine atom is very compact. In addition, the distance of the C-F bond is short and the bonding energy is higher than that of other bonds. This leads to a decrease in the cohesive energy between molecules and lowers the surface free energy of the polymer, thereby making the polymer less wettable and adhesive. G*4 can easily copolymerize with other acrylate-type monomers, also can polymerize with polymers that have a reactive functional group in their side chain such as (meth)acrylic acid, hydroxyalkyl acrylate and hydroxyalkyl acryl amide
