New anionic derivatives of mono and polyglycosides which are surface-active agents are described which anionic derivatives have the general formula ##STR1## wherein G is a glycosyl moiety which is derived from a reducing sugar selected from the group consisting of fructose, glucose, mannose, galactose, talose, gulose, allose, altrose, idose, arabinose, xylose, lyxose, ribose or mixtures thereof,

Ionic derivatives of alkyl mono and polyglycosides

There is provided a process for making diglyme soluble siloxane-imide copolymers consisting essentially of (a) heating a mixture of diglyme, azeotropic solvent, organic diamine and bis-aminoalkyl-terminated polydiorganosiloxane to reflux and (b) adding to the refluxing mixture of (a) an organic dianhydride of the formula ##STR1## where Ar is an aromatic or aromatic containing group and Y is oxygen or sulfur. Block copolymers are obtained if the bis-aminoalkyl-terminated polydiorganosiloxane is not added to the reaction mass until after the reaction of the organic diamine and organic dianhydride has been completed.

Method of making diglyme soluble siloxane-imide copolymers
