摘要:
An olefin polymer composition is provided comprising
(A) 100 parts by weight of a homopolymer of 1-butene composed substantially of 1-butene units or a copolymer of 1-butene and another alpha-olefin containing at least 60 mole % of units derived from 1-butene, and (B) 7 to 120 parts by weight of a homopolymer of propylene composed substantially of propylene units, a block copolymer of propylene and another alpha-olefin containing at least 50 mole % of units derived from propylene, or a random copolymer of propylene and another alpha-olefin containing at least 90 mole % of units derived from propylene, at least one of components (A) and (B) being partly modified with (D) an unsaturated carboxylic acid or its derivative and the composition not containing (C) a crystalline random copolymer of propylene and another alpha-olefin containing 50 to 87 mole % of units derived from propylene. A laminated structure comprising a substrate and a layer of a 1-butene polymer laminated thereto through an adhesive layer of the olefin polymer composition is also provided.
摘要:
A poly-1-butene resin composition comprising (A) 50 to 95 % by weight of poly-1-butene resin, and (B) 50 to 5 % by weight of a flexible polymer having a tensile modulus of not more than 1000 kg/cm², or (B′) 5 to 50 % by weight of a partially crosslinked olefinic thermoplastic elastomer obtained by dynamically heat-treating a mixture of (a) a peroxide-crosslinkable olefinic copolymer rubber, (b) a peroxide-decomposable olefinic resin and (c) a peroxide-noncrosslinkable hydrocarbon-type rubbery substance and/or a mineral oil-type softening agent. This poly-1-butene resin composition has superior water-proofness, heat resistance, suppleness and high-temperature chlorine-containing water resistance and is suitable for producing a thermofusible heat-resistant waterproof sheet.
摘要:
A non-crosslinked foam of a composition comprising (A) 72 to 98% by weight of a 1-butene polymer, and (B) 28 to 2% by weight of a propylene polymer, the percentages being based on the total weight of the 1-butene polymer and the propylene polymer.
