  • POLYESTER COMPOSITION
    Publication number: 20200407552
    Abstract: A polyester composition includes a polyester, a copolyester-ether, a styrene-butadiene copolymer, and a catalyst. The styrene-butadiene copolymer includes a butadiene monomer unit which is in an amount ranging from 12 wt % to 50 wt % based on a total weight of the styrene-butadiene copolymer. The styrene-butadiene copolymer is in an amount ranging from 0.2 to 4 parts by weight based on 100 parts by weight of the polyester.
