Abstract
Official abstract text for this publication.
The present invention generally relates to polyamide compositions having improved anti-delamination. More specifically, the present invention relates to novel polyamide compositions demonstrating improved anti-delamination, in which the compositions have at least one reinforcement agent.
First claim
Opening claim text (preview).
I claim: 1. A polyamide composition having improved anti-delamination comprising: (a) about 5 to about 30 wt. % of at least one low purity polyamide having a polyamide content of about 60 to less than 80 wt. %; (b) about 20 to about 55 wt. % of at least one high purity polyamide composition having a polyamide content of 95 to 100 wt. %, selected from: (i) at least one virgin polyamide; (ii) at least one high purity recycled polyamide; (iii) or mixtures thereof; (c) an o…
