AI Technical Summary
Technical Problem
Existing methods for modifying polymers, such as those using polyethylene and polyamide compositions, lack effectiveness in altering the physical properties of polymers with carbonyl and carboxyl groups.
Method used
A resin composition is created by melt-kneading a polymer with carbonyl and/or carboxyl groups with a terminal-modified vinyl-based polymer having amino groups at the molecular terminals, allowing for interaction and modification of the polymer's physical properties.
Benefits of technology
The resulting resin composition exhibits improved toughness, moldability, heat resistance, and impact resistance, with enhanced properties achieved through the interaction of carbonyl/carboxyl groups with amino groups.

Abstract
The present invention addresses the problem of providing a resin composition in which a polymer having a carbonyl group and / or a carboxyl group is modified so as to change the physical properties thereof. The problem is solved by a resin composition which is obtained by melt-kneading a component A that is a polymer having a carbonyl group and / or a carboxyl group and a component B that is a terminally modified vinyl polymer having one or more amino groups at an end of the molecule.
