reaction of polyols and saturated/unsaturated dibasic acids at 190-220℃ until

the expected acid value or viscosity is met. After reaction procedure, addition

of certain amount of styrene monomer to formed a unsaturated polyester

resin. It possesses good mechanical and electric properties, corrosion

resistance. Curing can occur at room temperature without any heating

equipment, and makes it easier to manufacture large objects.
