The formation of structural composites having low smoke release and low heat release properties by forming a sandwich comprising a non-woven fiber mat between woven glass fiber mats and impregnating said sandwich with a mixture of a bisoxazoline and a polyphenolic compound to form a prepreg which can be formed and molded at elevated temperatures is described.

Preparation of satisfactory asphaltic roofing fluxes from otherwise unsatisfactory fluxes is disclosed to involve addition of asphaltenes, and saturates in quantities which satisfy certain specified conditions. Air oxidation of a flux is shown to be surprisingly accelerated by the addition of highly branched saturates, especially in the presence of a carbonate oxidation catalyst.

Method and composition of asphaltic roofing fluxes

Liquid hydrocarbons are oxidized in the presence of a redox catalyst metal in combination with an alkali metal or alkaline metal promoter.

A hydrocarbon oxidate composition which comprises the reaction product of (a) a hydrocarbon oxidate, as described herein, or the metal salt thereof, with (b) a polyol as described herein, wherein the hydrocarbon oxidate composition comprises a wax oxidate and has a very high viscosity and increased molecular weight and is useful as a lubricant, grease, or protective coating.

Hydrocarbon oxidate composition

A hydrocarbon oxidate composition which comprises the reaction product of (a) a hydrocarbon oxidate, as described herein, or the metal salt thereof, with (b) a polyamine, as described herein, and (c) at least one copolymer of an olefin and a comonomer selected from (i) an unsaturated carboxylic acid; or (ii) a vinyl ester of a saturated carboxylic acid, wherein the hydrocarbon oxidate composition comprises a wax oxidate, a petrolatum oxidate or mixtures thereof and has a very high viscosity, increased molecular weight and sinewy characteristics and is useful as a lubricant, grease, or protective coating.

Sodium carbonate, sodium sesquicarbonate and other carbonate catalysts ground to fine particle sizes (95% plus passing through a 200 mesh sieve (75 .mu.m) are more active than commercially available grades of such catalysts when oxidizing asphalt fluxes, permitting reduction in oxidation time, reduction in required catalyst quantities and improvement in product quality.

Process for enhancing catalytic response of asphalt oxidation catalyst

Disclosed is a process for producing high grade asphaltic materials from low grade bituminous materials and the improved products resulting therefrom. More particularly, there is disclosed a process utilizing a particular type of oxidation catalyst in preparing novel high quality paving grade asphalt cements and novel roofing grade asphalts from poor and marginal quality bituminous materials. Also, the process can be used to prepare novel superior quality asphaltic materials from good quality bituminous flux feedstocks. This process consists of catalytically oxidizing asphalt fluxes, for example, in a single or multi-stage oxidation, using the particular type of catalyst disclosed hereinafter in each stage to chemically modify the flux so that the resultant asphaltic material meets physical requirements necessary for a finished product possessing good temperature susceptibility characteristics.
