Surface Properties of Unsaturated Polyester Resin/Siloxane-ester Copolymer BlendsPDMS;Surface Energy;Dynamic Contact Angle;Peel Strength;ESCA;In order to lower the surface energy of unsaturated polyester(UPE) resin, small amount of siloxane-ester copolymers were incorporated. The copolymers were synthesized by a condensation polymerization using ethylene glycol and hydroxy termintated polydimethylsiloxane as diols and maleic anhydride and phthalic anhydride as dibasic acids.
