A general formula for the product resin is as follows: ##STR1## wherein x is an integer of 1-5; R'=a polyamide ester chain of molecular weight 500-2000; where y is an integer of 1-3; R.sup.2 is independently at each occurrence the residue of a cyclic carboxylic anhydride bearing at least one free carboxyl group or ##STR2## where R.sup.3 is independently at each occurrence R' or a polyamide segment of up to 2000 MW.Type: GrantFiled: February 5, 1988Date of Patent: October 10, 1989Assignee: Union Camp CorporationInventors: Walter K. Bornack, Jr., Keith R. McNally

Patent number: 4871817Abstract: Disclosed are blends of (a) a polyetherimide and (b) a liquid crystal polymer. The liquid crystal polymer is an aromatic copolyester which exhibits melt anisotropy. The blends exhibit a higher heat distortion temperature higher flexural modulus and specific gravity over the polyetherimide component alone and have a higher tensile strength than that associated with the liquid crystal polymer alone.Type: GrantFiled: December 31, 1986Date of Patent: October 3, 1989Assignee: General Electric CompanyInventor: John A. Rock

Patent number: 4868047Abstract: An injection molding resin-type printed wiring board having an electric circuit pattern layer formed integrally on the surface thereof and having reduced warpage. In the printed circuit board, the injection molding resin includes a thermoplastic resin composition essentially comprising polyethylene terephthalate and containing a flaky inorganic reinforcing material. The inorganic reinforcing material comprises single-substance fine mica flakes or a mixture of fine mica flakes and short glass fibers.Type: GrantFiled: February 19, 1988Date of Patent: September 19, 1989Assignee: Furukawa Denki Kogyo Kabushiki KaishaInventors: Akira Hasegawa, Masayuki Ishiwa

Patent number: 4849469Abstract: Thermoplastic compositions and composites are produced which have fewer and smaller voids with more consistent dimensions compared to conventional unreinforced and fiber reinforced thermoplastics. The high modulus thermoplastic contains silicone semi-interpenetrating polymer networks which are formed by vulcanization within the thermoplastic and initiated during melt processing. Parts molded from the compositions are more homogeneous, with evenly distributed voids, thus reducing the possibility of strss fractures. The compositions are particularly useful in the molding in thick cross-section and variable thickness parts and have been found to have increased thermal stability.Type: GrantFiled: September 21, 1987Date of Patent: July 18, 1989Assignee: ICI Americas Inc.Inventors: Jane M. Crosby, MaryGail K. Hutchins, Susan K. Ward

Patent number: 4845150Abstract: This invention relates in general to the formation of films having a controlled molecular orientation prepared from rod-like extended chain aromatic-heterocyclic ordered polymers, and containing a binder in the micro-infrastructure. Such films have high tensile strength, modulus, and environmental resistance characteristics.Type: GrantFiled: June 22, 1987Date of Patent: July 4, 1989Assignee: Foster-Miller Inc.Inventors: Robert Kovak, Roland R. Wallis, Jr.
