Thermoplastic polyamide compositions

This invention relates to construction panels comprising metal-thermoplastic-metal laminates and a process for preparing same, said laminates possessing in combination critical service properties of low coefficient of linear thermal expansion, low inelastic ratio, and excellent flexural stiffness.

Metal-thermoplastic-metal laminates

This invention relates to construction panels comprising metal-thermoplastic-metal laminates and a process for preparing same, said laminates possessing in combination critical service properties of high heat distortion temperature, low coefficient of linear thermal expansion, low inelastic ratio, and lightness in weight.

Lightweight metal-thermoplastic-metal laminates exhibiting an improved combination of good formability and bending strength comprise a core layer of a thermoplastic material selected from certain partly crystalline polyamides and polyesters, and a metal layer of certain aluminum alloys laminated on each side of the core layer, said thermoplastic and metal layers having certain requirements with respect to thickness and tensile elongation, and, additionally for the metal, tensile offset yield strength.

Polyamide molding resin compositions are prepared by melt-blending a polyamide resin, a hydroxyl-functional elastomer and a succinic-functional coupling agent. The invention includes a process fore preparing the molding resin and the molded resin product.

High-impact polyamide molding resin compositions

The present invention relates to amino-functional photopolymer compositions and to photo-oxidation imaging processes utilizing such compositions. The amino-functional photopolymer compositions comprise amino-functional polymers. For example, other polymers or resins without amino-functionality may be incorporated to aid in adapting the compositions for use in particular applications as are discussed herein.

Amino-functional photopolymer compositions and photo-oxidation imaging

The present invention relates to amino-functional photopolymer compositions and to photo-oxidation imaging processes utilizing such compositions. The amino-functional photopolymer compositions comprise amino-functional polymers and photosensitizing agents which, when exposed to electromagnetic radiation in the presence of ordinary molecular oxygen, are cured, thereby forming a less soluble polymer. Where the irradiation has been done selectively or in an imagewise fashion, the compositions allow for the development of an image by virtue of the solubility or redispersibility differential between the exposed and unexposed portions of the compositions. The amino-functional photopolymer may be any of a large variety of types, but generally will comprise a polymer with two or more amino-functional groups. The polymer may be a soluble polymer or a small-particle-size microgel cross-linked polymer. The photopolymer may also comprise mixtures of soluble polymer and small-particle-size microgel cross-linked polymer. The amino-functional photopolymer may be rubbery, leathery or glassy. The photosensitizer incorporated in the amino-functional photopolymer composition may be any of a large number of photosensitizers which stimulate the production of singlet molecular oxygen; for example, tetraphenyl porphorin (TPP) and its derivatives and salts, fluoranthene, dinaphthalene, thiophene, rose bengal, etc. By varying the photosensitizer used in the compositions, the amino-functional photopolymer composition in the presence of ordinary molecular oxygen may be made sensitive to photo-curing by ultraviolet or visible irradiation, including green light and red light. The compositions may contain other constituents in addition to the amino-functional polymer and photosensitizer. For example, other polymers or resins without amino-functionality may be incorporated to aid in adapting the compositions for use in particular applications as are discussed herein.
