Publication number: 20100233405Abstract: Disclosed are stabilized blends of polyester and polyamide. The polymer blends are stabilized with A) a combination of stabilizers a) acetaldehyde scavengers and b) stabilizers selected from phenolic antioxidants, organic phosphorus stabilizers and lactone stabilizers or B) a combination of c) lactone stabilizers and d) stabilizers selected from phenolic antioxidants and organic phosphorus stabilizers. The present blends exhibit reduced color formation, a high level of whiteness/brightness and acceptably low haze formation upon heat treatment. The blends are useful to make bottles, containers and films for drinks, food and cosmetics and the like. The polyester is in particular polyethylene terephthalate, PET, and the polyamide is in particular polyamide-MXD6. Heat treatment is for example melt extrusion or solid state polymerization, SSP.Type: ApplicationFiled: March 11, 2010Publication date: September 16, 2010Applicant: CIBA CORPORATIONInventors: Stephen M.
