ABSTRACT:
New esters are described having the formula ##STR1## wherein R is a chemical bond or an inert linking group such as alkylene, oxa-alkylene, thia-alkylene, arylene, alkenylene or the like, R' and R" are H or lower alkyl and n is 2-3. They are made by the reaction of a bis-oxazoline or -oxazine with an equimolar amount of an acrylic acid: ##STR2## The compounds (I) are acrylic esters and are polymerizable and copolymerizable by the same general techniques used with other acrylic esters, thus producing solid resins useful as molding and coating materials. The oxazoline and oxazine rings in such resins are reactive with carboxyl groups; hence, the resins can be mixed with carboxy-containing polymers to form mixtures that readily cure upon mmold heat treatment to form hard, water-resistant and solvent-resistant, infusible resins.
