Title:
PREPARATION METHOD FOR ECO-FRIENDLY ACRYLIC MONOMER EPOXY RESIN MODIFIED VINYLESTER RESIN BY USING GLYCOLMODIFIED POLYETHYLENETEREPHTHALATE
Document Type and Number:
WIPO Patent Application WO/2023/210979
Kind Code:
A1
Abstract:
The present invention relates to a preparation method for an eco-friendly acrylic monomer epoxy resin modified vinylester resin by using glycolmodified polyethyleneterephthalate (PETG), the preparation method comprising: a first step of preparing monobasic acid by a reaction of maleic anhydride with an unsaturated polyester oligomer that is prepared by a reaction of glycol and polybasic acid with glycolmodified PETG obtained from waste generated from a PETG manufacturing process; a second step of preparing an epoxy resin modified vinylester resin oligomer by a reaction of an epoxy resin with the monobasic acid prepared in the first step; and a third step of preparing an acrylic monomer epoxy resin modified vinylester resin by dilution of the epoxy resin modified vinylester resin oligomer prepared in the second step with an acrylic monomer.
