The influencing factors of unsaturated polyester resin curing degree analysis
Unsaturated polyester resin, usually by unsaturated or saturated dibasic acid dibasic acid glycol unsaturated glycol polycondensation of with ester bond of linear polymers and unsaturated double bond. Usually, polyester melt polycondensation reaction was conducted in 190 ~ 220 ℃, until the desired acid value (or viscosity), at the end of the polyester melt condensation reaction, add a certain amount of vinyl monomer, match into sticky liquid, the polymer solution is called unsaturated polyester resin.
