Abstract
Abstract A resinous composition, having excellent toughness, flexibility, heat resistance and moldability, comprises (A) from 5 to 98% by weight of a polyamide and (B) from 95 to 2% by weight of a polyolefin modified with from 0.001 to 10% by mole based on all polymer components of a component having at least one functional group selected from the groups represented by the following general formulas (I), (II) and (III); ##STR1## wherein R 1 denotes an organic group and R 2 , R 3 , R 4 and R 5 denote a group selected from the groups consisting of hydrogen atom and organic group respectively.

Total Claims: 9
Claim 1
Independent Claim
121 words
A resinous composition comprising (A) from 5 to 98% by weight of a polyamide and (B) from 95 to 2% by weight of a polyolefin modified with from 0.001 to 10% by mole based on all polymer components of a component having at least one functional group selected from the groups represented by the following general formulas (I), (II) and (III): wherein R 1 , R 2 , R 3 , R 4 and R 5 in said general formulas (I), (II) and (III) are independently selected from the group consisting of a group represented by the formula: ##STR36## wherein n denotes an integer of 2 to 10, alkyl groups having 1 to 4 carbon atoms, phenyl group and benyl group.
