METHOD FOR PREPARING EPOXY GROUP-GRAFTED POLYKETONE COMPATIBILIZER AND FOR PRODUCING POLYKETONE ALLOY RESIN HAVING IMPROVED HEAT RESISTANCE USING SAME

WIPO Patent Application WO/2018/124540

A1

According to a preferred example of the present invention, provided is a polyketone composition having improved compatibility and comprising a linear alternating polyketone composed of carbon monoxide and at least one olefinically unsaturated hydrocarbon, polybutylene terephthalate, and a compatibilizer. The compatibilizer is characterized in that styrene, glycidyl methacrylate are grafted on a polyketone (PSG). The polyketone composition with improved compatibility of the present invention has an effect of improving the compatibility by forming a chemical bond between a grafted epoxy group of the compatibilizer and a hydroxyl group of polybutylene terephthalate. According to another preferred example of the present invention, provided is a polyketone composition having improved tensile strength and comprising a linear alternating polyketone, composed of carbon monoxide and at least one olefinically unsaturated hydrocarbon polyphenylene ether resin or polyester resin, and a compatibilizer. The compatibilizer comprises an epoxy active group or an anhydride group and is characterized by at least one or two selected from the group consisting of a polyketone grafted with styrene, and glycidyl methacrylate (POK-g-styrene/GMS, PSG), a polyketone grafted with glycidyl methacrylate (POK-g-GMA), styrene-maleic anhydride (SMA), ethylene methacrylate, methyl methacrylate-glycidyl methacrylate-ethyl acrylate (MGE), an ethylene-octene elastomeric elastomer grafted with maleic anhydride (EOR-MA), ethylene propylene rubber grafted with maleic anhydride (EPR-MA), and a polymer of ethylene, butyl acrylate, and glycidyl methacrylate. The compatibilizer has an effect of improving heat resistance of conventional polyketones such as tensile strength, color, etc. upon exposure to heat for a long time by forming a chemical bond with a polyether resin or a polyester resin.
