Abstract

Ester condensation products.-Polyhydric alcohol-polybasic acid condensation products in the fusible state are treated with an acylating agent, which may be the chloride or anhydride of an aliphatic or aromatic acid. Excess of the acylating agent is removed by distillation under atmospheric or reduced pressure, and the resin is then polymerized. This process of acylation lowers the rate of polymerization at a fixed temperature, but enables polymerization to be effected at higher temperatures and, therefore, more quickly than usual. Simple polyhydric alcohol-polybasic acid resins may be treated, and also mixtures of such resins, resinous complexes from two or more acids and two or more alcohols, such resins plasticized with, for example, oleic acid, and any of the above mixed with any natural or synthetic resin. Specific materials referred to are glycol, glycerol, phthalic, succinic, and citric acids, oleic acid and colophony, acetic anhydride and benzoyl chloride. Specifications 24254/12, 308,671, 317,225 and 328,190, [all in Class 2 (iii), Dyes &c.], are referred to.
