  • Publication number: 20240067819
    Abstract: The present invention relates to a heat resistant composition comprising polycarbonate and polyester, wherein said polyester comprises poly(ethylene terephthalate), that is substantially free of isophthalic acid moieties. The composition has a Vicat softening point, as determined by ISO-306 B120 at a load of 50N and a speed of 120° C./hr that is higher than the Vicat softening point of an otherwise identical composition wherein the poly(ethylene terephthalate) component contains isophthalic acid moieties. The present invention further relates to an article comprising or consisting of such a composition.

  • Patent number: 8784719
    Abstract: Reinforced polyimide compositions that include a reinforcing filler and a polyamide flow promoter improve flow promotion while maintaining other mechanical, thermal, flame and/or electrical properties of the compositions. The compositions may include an inorganic or organic reinforcing filler, a polyimide resin such as polyetherimide or polyamideimide and a small amount of an aromatic or aliphatic polyamide as the flow promoter. The resulting compositions may be used in thinner-wall applications while still retaining the advantageous physical properties of reinforced polyimide compositions not having the flow promoter. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present invention.
