An adduct of ethylene oxide and 2,2,4-trimethylpentane-1,3-diol is useful as a reactant-diluent in water-borne coatings Typically the adduct functions as a cosolvent, a flow control aid, and a reactive glycol which is incorporated in the final cured coating

Aqueous coating of curable binder, cross-linker and oxyethylated 2,2,4-trimethylpentane-1,3-diol

The process of carrying out aldol condensations either batch-wise or continuously without catalyst with formaldehyde and another aldehyde in the presence of esterifying acid at a temperature of from about 150° C to about 280° C., with from about 170° C. to about 190° C. being preferred.

Noncatalyzed aldol reaction

This invention relates to an improved method for the catalyzed condensation of aldehydes in the liquid phase to form 1,3-glycol monoesters utilizing tin metal or a tin oxide catalyst. Condensation can be visualized as an aldol condensation followed by a Tischenko reaction between the aldol and a third molecule of aldehyde. In its simplest form the condensation can be illustrated by the following general formula ##STR1## R or R1 =Hydrogen or alkyl group of 1 to 20 carbon atoms or aromatic groups. R and R1 can also be part of a cyclic system.

Catalytic condensation of aldehydes to 1,3-glycol monoesters

A plastic additive comprising the mixed ester reaction product of 2,2,4-trimethylpentane-1,3-diol monoisobutyrate, a monohydric alcohol of the formula ROH wherein R is straight or branched chain alkyl of 1 to 12 carbon atoms or benzyl and dimethyl terephthalate. The additive is particularly useful as a processing aid for rigid polyvinyl chloride and as a modifier for thermoplastic acrylic coatings.

Mixed ester plastic additive

Novel heat-curable compositions are obtained by combining a bis(2-hydroxyethyl)dicyclopentadiene-containing polyester and an unsaturated polyester. These compositions can be cross-linked by heating at temperatures above 135° C., and do not require cross-linking agents or radical initiators. The compositions of the present invention are useful as coatings and adhesives having superior qualities.
