PURPOSE: To provide a bondable resin compsn. which gives a laminated sheet having excellent interlaminar bond strength, such as a polyamide resin-laminated sheet, by mixing a specified modified polyolefin with an ethylene/α,β-unsaturated carboxylic acid copolymer (metal salt). n CONSTITUTION: 100pts.wt. mixture (A) of 60W100wt% ethylene/3C or higher α-olefin copolymer having a density of lower than 0.91g/cm 3 and 40W0wt% crystalline polyolefin resin is blended with 0.05W2pts.wt. unsaturated carboxylic acid (anhydride) (B) (e.g., maleic anhydride) and 0.001W0.1pt.wt. org. peroxide (e.g., benzoyl peroxide) and the mixture is melt-kneaded. 20W55wt% resulting modified polyolefin is mixed with 80W45wt% ethylene/α,β-unsaturated carboxylic acid copolymer (metal salt) (e.g., ethylene/acrylic acid copolymer) and 0W25wt% crystalline polyolefin resin to obtain the titled compsn. n COPYRIGHT: (C)1987,JPO&Japio |
