The Hyperbranched Polyester Reinforced Unsaturated Polyester Resin. [PDF]

Polymers (Basel), 2022
We report a method of reinforcing and toughening unsaturated polyester resin (UPR) with a kind of hyperbranched polyester (HBP-1). Polyethylene glycol with different molecular weight was used as the core molecule of the preparation reaction, and the reaction product of phthalic anhydride and glycerol was used as the branching unit.
