A thermoplastic resin composition comprising: (A) 1 to 100 parts by weight of a modified polyolefinic polymer containing one structural unit having a glycidyl group represented by general formula (I) per 2 to 1,003 repeating olefinic units, wherein Ar represents a C6 to C23 aromatic hydrocarbon group having at least one glycidyloxy group and R represents hydrogen or methyl, and (B) 100 parts by weight of polyamide. The composition gives a molding wherein a strong affinity is generated at the boundary between the polyolefin and the polyamide and which has, as a result excellent, mechanical properties such as impact resistance and good surface properties.

Why it's free to use
- Filed October 1, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended October 1, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 1, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
