Abstract: Title: COMPOSITIONS CONTAINING BASIC METAL SALTS AND/ OR NON-NEWTONIAN COLLOIDAL DISPERSE SYSTEMS AND VINYL AROMATIC CONTAINING POLYMERS The present invention relates to modified nonNewtonian colloidal disperse systems exhibiting improved thickening power, particularly when diluted. These compositions are useful as high-solids, thermosetting caulks, molding compositions, extruding compositions and the like, but are particularly suitable for use as high solids thermosetting coating compositions. These coating compositions are heat-stable and sag-resistant. The compositions of this invention comprise a mixture of (B) at least one non-Newtonian colloidal disperse system comprising (B-1) solid metal-containing colloidal particles, (B-2) a liquid dispersing medium, and (B-3) at least one organic compound which is soluble in said dispersing medium, the molecules of said organic compound being characterized by a hydrophobic portion and at least one polar substituent; and (C) at least one hydrogenated block copolymer of a vinyl aromatic monomer and an aliphatic conjugated diene. Optionally, the compositions also contain (D) a substantially inert, normally liquid diluent. The invention also relates to methods of coating metal surfaces with the compositions of the invention described above as well as compositions comprising mixtures of neutral and/or basic metal salts of organic acidic materials and the copolymers (C) described above.

Abstract: L-2365C Title: ACRYLATE POLYMER MODIFIED ASPHALT COMPOSITIONS Modified asphalt compositions are described which comprise (A) asphalt, and (B) a minor effective amount, sufficient to improve the durability of the asphalt in service, of at least one hydrocarbon-soluble acrylate polymer of the formula x wherein R1 is a lower alkyl group containing from 1 to about 4 carbon atoms, R2 is a mixture of alkyl groups containing from about 4 to about 20 carbon atoms, and x is an integer providing a weight average molecular weight (Mw) to the acrylate polymer of about 5000 to about 1,000,000. Generally, the modified asphalt compositions will contain from about 0.01 to about 10% by weight, based on the weight of the asphalt, of the acrylate polymer as defined. The modified asphalt compositions of the present invention are useful in roofing and in preparing aggregate-containing asphalt concretes which can be employed as paving compositions.
