MERCEDES-BENZ

Model:

E-CLASS

Year:

2010

US Patent:

47465662, May 24, 1988

Filed:

May 6, 1987

Appl. No.:

7/046560

Inventors:

Mark S. Connolly - Wilmington DE

Assignee:

E. I. DuPont de Nemours and Company - Wilmington DE

International Classification:

B32B 2700

US Classification:

428290

Abstract:

Novel copolyesters derived from (a) aromatic diols, (b) dicarboxylic acids and (c) aromatic hydroxycarboxylic acids, in which the aromatic hydroxycarboxylic acid component (c) comprises 20 to 60 mole % of the copolyester and in which t-butyl-4-hydroxybenzoic acid constitutes 25 to 100 mole % of the aromatic hydroxycarboxylic acid component (c), are disclosed. These copolyesters are anisotropic and fabricable in the melt. They generally can be processed using conventional thermoplastic shaping techniques at temperatures below 350. degree. C. into moldings, fibres and films which have outstanding mechanical properties.

Assignee:

E. I. Du Pont de Nemours and Company - Wilmington DE

International Classification:

B32B 2700

US Classification:

428290

Abstract:

Novel copolyesters derived from (a) aromatic diols, (b) dicarboxylic acids and (c) aromatic hydroxy carboxylic acids, in which t-butylhydroquinone constitutes 55 to 95 mole % of the diol component (a) are disclosed. These copolyesters are anisotropic and fabricable in the melt. They generally can be processed using conventional thermoplastic shaping techniques at temperatures below 350. degree. C. into moldings, fibers and films which have outstanding mechanical properties.
