    摘要： A process for recovering bitumem from oil-in-water (O/W) emulsions is disclosed wherein water soluble demulsifiers are used. These demulsifiers are water soluble polyethers prepared by the reaction between certain diepoxides and poly(ethyleneoxy) glycols. To resolve the bituminous petroleum emulsions, the process is carried out between 25.degree. and 160.degree. C. wherein the demulsifier of the invention is contacted with the bituminous emulsion.

    摘要： Amidamines of the following formula are described: ##STR1## where R is independently hydrogen or lower alkyl of 1 to 4 carbon atoms;R' is an alkyl group if k is 1, or an alkylene group if k is greater than 1; where R' has 2 to 18 carbon atoms;R" is independently lower alkylene of 2 to 4 carbon atoms;R'" is independently straight or branched lower alkylene of 2 to 6 carbon atoms;x is independently 1 to 200;y is independently 1 to 300;z is independently 1 to 200;p is independently 2 to 11; andk is from 1 to 8; where the x and z groups may be distributed in blocks or randomly.These compositions are made by reacting a cyclic lactam with an etheramine. Incorporation of increasing quantities of the polyetherpolyamine did not decrease the crystalline melting point (T.sub.m) of the resulting copolymer. The polyamidopolyfunctional amines (poly(amide-ether-amide) triblock copolymers) have a relatively low modulus and retain higher use temperatures than current polyetheramide segment block copolymers. The polyamidopolyether amines may be further interconnected through reaction with dicarboxylic acids, esters and the like.
