Title:
POLYAMIDE THERMOPLASTIC COMPOSITIONS WITH IMPROVED IMPACT STRENGTH PROPERTIES
Document Type and Number:
WIPO Patent Application WO2001074947
Kind Code:
A3
Abstract:
The invention concerns a polyamide thermoplastic composition comprising: 50 to 98 parts of a non-diamine polyamide (A1); 0.2 to 40 parts, preferably 0.2 to 9 parts of a diamine polyamide (A2), said polyamide (A2) being different from the polyamide (A1) and the mass ratio (A2)/(A1) being less than 1; 1 to 60 parts, preferably 1 to 30 parts of a reactive impact modifier (B) or a mixture of modifiers comprising at least a reactive impact modifier. The invention also concerns an impact modifying composition and the method for preparing said thermoplastic composition using said impact modifying composition.
