(57) [Abstract] (Modified) [Problem] To improve the weak points of the physical properties of pet resin and polyolefin, a polyester-polyolefin block copolymer is used, and impact resistance, heat resistance, tensile strength, etc. Excellent in food containers, packaging materials, cushioning materials, heat insulating materials, A method for producing useful molded articles such as packaging materials, partition boards, and boards. (A) Linear saturated polyester 95-5 Parts by weight, (b) 5-95 parts by weight of a polyolefin containing one or more carboxylic acid groups in the molecule, and (c) compounds 0-10 containing two epoxy groups in the molecule as a binder. 0.1 to 5 parts by weight of a mixture of 0 to 100% by weight of a compound containing 0% by weight and an average of 2.1 or more epoxy groups, (D) A mixture comprising 0.01 to 1 part by weight of a metal salt of an organic acid as a binding reaction catalyst in a total amount of 100 parts by weight of the above (a) and (b) is prepared in advance by melting point of the polyester / polyolefin. Heat at the above temperature. |
