Properties of polyimide-g-polyglutarimide blends
- Rohm and Haas Corp., Bristol, PA (United States)
Polyglutarimides, at least partially grafted to polyamides (such as Nylon-6) can be prepared by a reactive extrusion process described in an accompanying paper. These blends, in turn, exhibit some interesting properties such as clarity, toughness, resistance to heat and moisture effects, and have excellent barrier properties. The poly-glutarimides may also be used in small amounts to vary the viscosity and melt strength of the polyamide since the grafting process builds molecular weight via the grafting process. For instance, an extrusion grade polyamide can easily be made into a blow molding grade by the use of small amounts of polyglutarimide by in-situ grafting during processing. Blends of these grafted polymers may also be impact modified with a number of particulate or elastomeric impact modifiers. Blends with {open_quotes}supertough{close_quotes} impact can be prepared which also possess high heat resistance and excellent solvent resistance properties simultaneously.
