Abstract

Ester-like conversion products of casein are obtained by reacting an alkylene oxide with a neutral or weakly acid aqueous suspension of casein until the product exhibits an alkaline character after neutralization of the acid if employed, for example, by ammonia. Water-soluble fatty acids, such as acetic acid, are preferred. Ethylene, propylene or butylene oxide, glycide, or mixtures of alkylene oxides obtained by conversion of commercial mixtures of unsaturated aliphatic hydrocarbons may be employed. In the case of ethylene oxide, 10--50 per cent, and generally 20--30 per cent thereof by weight of the casein may be used. Reaction may be effected up to 90 DEG C., 40--80 DEG C. being preferred. The products may be employed in the production of adhesives and shaped artificial masses, and for sizing and finishing purposes in the textile and related industries. They are soluble in dilute acids, for example, 2 or 3 per cent acetic acid.
