Method for the preparation of water-borne coating compositions using

The present invention relates to water-borne thermoplastic polyhydroxyether resins having narrow polydispersity (M.sub.w /M.sub.n &lt;4.0 and M.sub.n &gt;7,000 &lt;12,000), and the use of such resins in water-borne coating compositions.

Novel phosphorylated compositions of a vinyl chloride copolymer or terpolymer, a phenoxy resin, a hydroxyalkyl acrylate or methacrylatelactone adduct or a reaction product of a normally solid pendant-hydroxyl-containing thermoplastic polymer having at least 8 hydroxyl groups per molecular chain and an adduct which is the product of either a hydroxylalkyl acrylate or methacrylate or a lactone-acrylate adduct and an organic diisocyanate having improved dispersion characteristics suitable for use in applications such as magnetic recording media.

Phosphorylated reaction products and compositions incorporating such

Novel vinyl chloride copolymers including a hydroxyalkyl acrylate or methacrylate or allyl alcohol, an epoxy-containing vinyl monomer and an acid functionality from either certain carboxylic acid-containing monomers or a phosphorus ester moiety in selected proportions provide suitable binder resins for applications such as magnetic recording media, imparting desirable thermal stability together with enhanced dispersion and magnetic property characteristics and miscibility with elastomers employed in such media.

Novel vinyl chloride resins and compositions incorporating such resins

Waterborne, neutralized, carboxyl-bearing phenoxy resin with which is blended a relatively soft, neutral, non-carboxyl-bearing modifier resin. A coalescing solvent is preferably included in the aqueous blend.

Modified waterborne phenoxy resins

Flexible, self-cross-linking binders, useful for, e.g., paints and magnetic media composites, are prepared from hydroxyl-containing thermoplastic polymers reacted with condensates of diisocyanates and unsaturated esters. They can be cured with an electron beam.

Flexible, self-cross-linking binders

A process for the polymerization or copolymerization of an olefinically unsaturated monomer which comprises contacting the monomer with a chromium metal catalyst composition which is the product obtained by adsorbing a chromium metal complex which contains allyl hydrocarbon radicals with an inert inorganic oxide support which has --OH groups on its surface and which is free from adsorbed water, said monomer being an olefinically unsaturated monomer other than a polar vinyl monomer.

An apparatus for the continuous production of a curable polyurethane froth which apparatus comprises separate sources of a polyol, an isocyanate, a catalyst and an inert gas, means including separate conduits for feeding said polyol, isocyanate and inert gas separately and under pressure at controlled flow rates from said sources to a mixing device containing inlet openings to receive said polyol, isocyanate and inert gas, means for mixing said polyol, isocyanate and inert gas to produce a froth, and an outlet opening for the resulting froth, means for delivering the froth from said mixing device to a second mixing device, a conduit for feeding the catalyst under pressure at a controlled flow rate to the second mixing device, and means for mixing the froth and catalyst, said mixing device containing inlet openings to receive the froth and catalyst and an outlet opening for the resulting catalyzed froth and means for delivering the catalyzed froth from the mixing device onto a substrate.

Apparatus for producing a curable polyurethane froth

Described herein is a frothable thermosetting polyurethane-forming composition, a process for producing a curable froth from said composition, a process for applying the curable froth to a substrate and a cured cellular polyurethane produced from the curable froth.
