摘要:
The present invention is concerned with thermoplastic terephthalic acid copolyesters which crystallize more rapidly than homopolyethylene terephthalate and are based on a diol component which is about 98 to 99.9 mol % of ethylene glycol and the balance 2-ethylhexane-1,3-diol. The acid component may be up to about 10.0 mol % of other than terephthalic acid or its dimethyl ester.This invention is also concerned with a process of synthesizing such copolyesters by esterifying or transesterifying the acid and diol components between about 150.degree. and 250.degree. C. in the presence of appropriate catalysts. The condensation product may be subject to polycondensation at about 200.degree. to 300.degree. C. under reduced pressure in the presence of esterification catalysts. In a preferred embodiment the 2-ethylhexane-1,3-diol is added after the initial reaction between the acid component and the ethylene glycol and preferably after the degree of polycondensation is greater than 4.

An agent suitable for imparting antistatic properties to plastics is disclosed. The incorporation of small amounts of perfluoroalkylsulfonic acid salt in plastic resins, notably thermoplastic resins was found to be effective for this purpose.
摘要:
A transparent heat-absorbent multi-layer structure comprising, (A) a first layer, and (B) a second layer is described. The first layer (A) contains at least one organic infrared absorber (e.g., a phthalocyanine) and at least one ultraviolet absorber (e.g., a benzotriazole), and the second layer (B) contains at least one ultraviolet absorber and is substantially free of organic infrared absorbers. The first layer (A) is the only layer in the multi-layer structure that contains an organic infrared absorber. Also described is a method of preparing the multi-layer structure. Molded articles that may comprise the multi-layer structure of the present invention include glazings, such as automotive glazings.
摘要:
The present invention provides a coating which contains a primer layer on a substrate with a scratch resistant layer adhered to the primer, wherein the primer layer contains a hardened epoxy resin prepared from a hardener and a multi epoxy-functional compound and the scratch resistant layer contains an epoxide group containing hydrolyzable silane. The coating may find use in coated products such as sheets, spectacles, optical lenses, automobile screens and plastic spray screens.
