Abstract
This invention provides a modified polyolefin resin composition that contains a large amount of an unsaturated carboxylic acid or an anhydride thereof, and that can inhibit an increase in fluidity after graft modification due to little influence of a reaction residue, wherein the resin composition when used as a compatibilizer for reinforced fiber plastics provides a molded article with excellent mechanical properties such as bending strength and impact resistance.
Claims8
A resin composition comprising a reaction product obtained by reacting a propylene-based polymer (A), a diene-based elastomer (B), and an unsaturated carboxylic acid or anhydride thereof (C),
- wherein
- the content of the unsaturated carboxylic acid or anhydride thereof (C) is 2.0 mass % or more of the entire resin composition,
- the melt mass flow rate of the resin composition measured at 190° C./2.16 kg as defined in JIS K 7210 is 2 g/10 min or more and 500 g/10 min or less,
- the content of a reaction residue derived from the unsaturated carboxylic acid or anhydride thereof (C) is less than 2.0 mass % of the entire resin composition,
- the content of a volatile hydrocarbon compound in the resin composition is 0.5 mass % or less of the entire resin composition, and
- the content of the diene-based elastomer (B) is more than 10 mass % and 50 mass % or less relative to the total amount of the propylene-based polymer (A) and the diene-based elastomer (B).
