RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2021/059969
Kind Code:
A1
Abstract:
[Problem] To provide a modified polyolefin resin composition that has a high content of an unsaturated carboxylic acid or an anhydride thereof, is capable of suppressing a rise in fluidity after graft modification with little influence of reaction residues, and has excellent mechanical properties such as bending strength and impact resistance of a molded article when used as a compatibilizing agent of a fiber-reinforced plastic. [Solution] A resin composition containing a reaction product obtained by reacting a propylene polymer (A), a diene elastomer (B), and an unsaturated carboxylic acid or an anhydride thereof (C), wherein the content of the unsaturated carboxylic acid or anhydride thereof (C) of the resin composition is 2.0 mass% or higher, the melt mass flow rate of the resin composition measured at a 190°C/2.16 kg as stipulated in JIS K-7210 is 2-500 g/10 min inclusive, and the reaction residue derived from the unsaturated carboxylic acid or anhydride thereof (C) in the resin composition is less than 2.0 mass%.
