  • Modified acrylic block copolymer, method for producing same, and intended use of same
    Patent number: 9796890
    Abstract: A modified acrylic block copolymer is obtained by a method comprising subjecting a block copolymer (C) to a reaction with an amine compound, wherein the block copolymer comprises a polymer block (A) comprising a (meth)acrylic acid ester unit (a) and a polymer block (B?) comprising a (meth)acrylic acid ester unit (b?), the (meth)acrylic acid ester unit (a) is structurally different from the (meth)acrylic acid ester unit (b?), thereby partly or entirely converting the (meth)acrylic acid ester unit (b?) into at least one selected from the group consisting of an N-substituted (meth)acrylamide unit (d), a (meth)acrylic acid unit (c), and an N-substituted bis((meth)acryl)amide unit (e).

  • Thermoplastic polymer composition, molded product, and multilayer structure
    Patent number: 7354654
    Abstract: A thermoplastic polymer composition having good flexibility and excellent barrier properties with respect to gases and organic liquids, which can be adhesively bonded to a polyolefin resin, this composition comprising an ethylene-vinyl alcohol copolymer (A), a polymer mixture (B) composed of a block copolymer (I) mainly comprising a vinyl aromatic polymer block and a conjugated diene polymer block which may be hydrogenated, and a rubber softener (II), and a polyolefin resin (C), wherein at least part of the block copolymer (I) is modified at a modification ratio of 0.05 wt. % or higher so as to have a functional group capable of reacting with the ethylene-vinyl alcohol copolymer (A), wherein the ISO type A hardness of the thermoplastic polymer composition is not less than 30 and not higher than 90, and the oxygen permeation coefficient is 20,000 mL·20 ?m/m2·day·atm or less.
