Abstract of the Disclosure Process for the manufacture of terpolymers comprising the steps of (a) preparing an ethanol solution of a monomer mixture of acrylic acid, ethyl acrylate and t-butylacrylamide; (b) indroducing a first minor portion of the monomer mixture into refluxing ethanol; and then (c) without further heating continuously and simultaneously adding the remainder portion of the monomer mixture and an ethanol solution of a polymerization initiator to the reaction mixture over 1 to 3 hours at a rate that maintains the reflux of ethanol in the reac- tion mixture provided that the addition of the monomer mixture is completed 15 to 30 minutes before the addition of the initiator is completed. The carboxylic groups of the terpolymer thus made can be neutralized and optionally diluted to a hair fixing formulation in ethanol for use as air-pump spray or as a spray charged to an aerosol can for performing a desirable balance of water solubility and curl retention properties.
