摘要

FIELD : chemistry.SUBSTANCE : present invention relates to a resin composition for moulded articles; moulded article; a sheet containing a resin composition and a tube containing a resin composition. Said resin composition contains propylene resin (a), a hydrogenated block copolymer (b) and a hydrogenated block copolymer (c). Hydrogenated block copolymer (b) contains a polymer block (B1) having butadiene and/or isoprene as the main component and a polymer block (S) having styrene as the main component. Hydrogen block copolymer (c) comprises B2 block, having butadiene and/or isoprene and styrene as main components. Also, the hydrogenated block copolymer (b) and/or (c) further comprises a polymer block (S). Weight ratio of the content of the hydrogenated block copolymer (b) to the content of the hydrogenated block copolymer (c), (b)/(c) ranges from 90/10 to 10/90. Weight ratio of the content of the polypropylene resin (a) to the total content of the hydrogenated block copolymer (b) and the hydrogenated block copolymer (c), (a)/((b)+(c)) ranges from 10/90 to 90/10. Prior to hydrogenation, polymer blocks (C), (B1) and (B2) differ in the number of vinyl bonds.EFFECT : technical result is creation of resin composition with improved ratio between flexibility, transparency, anisotropy, low adhesion and low-temperature resistance to impact loads; moulded articles from compositions of polypropylene resin are used as a package for food products, clothes and in medicine, including infusion tubes and infusion bags and the like.15 cl, 16 tbl, 28 ex
