High solids containing thermoset resins are made by admixing the adduct of an alkylene oxide and a hydroxyalkyl (meth)acrylate with one or more polymerizable vinyl monomers. A more preferred method is to blend a co-reactive flexibilizing homopolymer or copolymer of the adduct with a rigid vinyl polymer or copolymer to form a thermosettable mixture of polymers. The adduct or polymer-containing adduct is present in amount of from about 5 to about 95% by weight of the monomer or polymer mixture.

Acrylic coating compositions and method therefor

The weatherability of acrylic coatings is enhanced by incorporating into the acrylic polymer hydroxybutyl acrylate or hydroxybutyl methacrylate.

Thermoset acrylic coatings having improved gloss retention

The invention is a process for obtaining pure BAEE from the crude reaction mixture of H.sub.2 SO.sub.4 and monoethanolamine. It consists of five major operations, which are:

Process for making 2-aminoethyl ether

Water-dispersible polymers of an acid salt of 2-aminoalkyl esters of monounsaturated monocarboxylic acid and at least one comonomer are prepared by dissolving the salt of that ester in a coupling solvent, mixing the comonomers as a separate feedstock and bringing the monomers together in a polymerization zone at a controlled rate so that the monomers remain in solution and polymerizing to substantial completion.

Water-thinnable coating compositions from aminoalkyl carboxylate

Solvent soluble epoxy-containing compositions prepared by polymerizing ethylenically unsaturated monomers such as alkyl acrylates in the presence of the reaction product of a liquid epoxy resin such as a diglycidyl ether of bisphenol A and acrylic acid and/or methacrylic acid. These compositions are useful in the preparation of coatings.

Epoxy coating compositions with improved weatherability

A nonvolatile amine, which is at least partially neutralized with a mixture of hydrochloric acid and either hydrobromic or hydriodic acid, dissolved in a solvent, is mixed with a volatile ketone and a polyglycidyl ether or ester to result in a thermosettable resin composition having extended pot life in bulk and a fast cure rate in thin sections.

Fast curing polyepoxide coating compositions with good pot life

Water-soluble acidified aminoalkylated interpolymers have enhanced properties when the pendant aminoalkylate groups are acidified with a mixture of hydrochloric acid and hydrobromic acid. In addition, coating compositions of such interpolymers, polyepoxides and water miscible solvents have improved cure rates when compared to compositions wherein the interpolymer is acidified with only one acid.

Water thinnable coating compositions from aminoalkylated interpolymers

Water swellable polyacrylate articles are made from a solution of the polyacrylate having an effective amount of a soluble crosslinking agent therein by heating and/or drying the solution. The polyacrylate solution is made from a polyacrylate by saponification and the crosslinking agent is then added.

Novel cellulosic sizing agents are described. They are ring-opened aziridinyl homopolymers of ##EQU1## wherein R.sub.1 and R.sub.2 are hydrogen or lower alkyl; R.sub.3 is hydrogen or methyl; R.sub.4 is an organic hydrophobic group (e.g., C.sub.8 -C.sub.24 alkyl radical); and X is oxygen or amido nitrogen. The above homopolymers can also be blended with cationic starch to form useful sizing compositions. These sizing agents are normally employed as aqueous emulsions. E.g., paper having excellent sizing properties was prepared from a paper pulp containing a mixture of cationic starch and poly[stearyl 3-(1-aziridinyl)propionate].
