摘要： An object of the present invention is to obtain a resin composition having further improved adhesiveness with a substrate layer when used as an adhesive layer in a multilayer body, and a multilayer body with superior adhesive strength between layers that includes a layer composed of the resin composition.
The present invention relates to a resin composition and a multilayer body that includes the resin composition layer, the resin composition being characterized by containing a propylene-based polymer (A) in the range of 5 to 70% by weight; a soft propylene-based polymer (B) in the range of 30 to 95% by weight; a propylene-based polymer (C) graft-modified with an ethylenically unsaturated monomer, in the range of 0.1 to 20% by weight; a polyethylene (D) in the range of 0 to 20% by weight; and an ethylene/α-olefin random copolymer (E) in the range of 1 to 30% by weight, provided that a total amount of (A), (B), (C), (D), and (E) is 100% by weight.-

摘要： The present invention aims to provide a lubricating oil composition having a higher viscosity index (lower temperature dependence of viscosity) and excellent in low-temperature viscosity characteristics. The present invention relates to a lubricating oil composition including a resin (A) and a base oil (B), wherein the resin (A) satisfies the following requirements (A-1) to (A-3), the base oil (B) satisfies the following requirement (B-1), and a content ratio between the resin (A) and the base oil (B) is such that the resin (A) is in a range of 0.01 to 50 parts by mass per 100 parts by mass in total of the resin (A) and the base oil (B). (A-1) the resin (A) is a polymer including a constituent unit derived from 4-methyl-1-pentene in a range of 60 to 99 mol% and a constituent unit derived from an α-olefin having 2 to 20 carbon atoms (excluding 4-methyl-1-pentene) in a range of 1 to 40 mol% (provided that 4-methyl-1-pentene and the α-olefin is 100 mol% in total); (A-2) intrinsic viscosity [η] measured in decalin at 135°C is in a range of 0.01 to 5.0 dl/g; (A-3) a melting point (Tm) is in a range of 110 to 150°C as determined by differential scanning calorimetry (DSC); and (B-1) kinematic viscosity at 100°C is in a range of 1 to 50 mm 2 /s.
