TERPOLYMERS BASED ON .ALPHA.,.BETA.-UNSATURATED DICARBOXYLICANHYDRIDES .ALPHA.,.BETA.-UNSATURATED COMPOUNDS AND POLYOXYALKYLENE ETHERS OF LOWER UNSATURATED ALCOHOLS |
摘要 |
Terpolymers based on .alpha., .beta.-unsaturated dicarboxylic an- hydrides, .alpha., .beta.-unsaturated compounds and polyoxyalkylene ethers of lower unsaturated alcohols. The present invention relates to terpolymers based on .alpha., .beta.-unsaturated dicarboxylic anhydrides, .alpha., .beta.- unsaturated compounds and polyoxyalkylene ethers as defined in claim 1, and also a process for preparing the same as defined in claim 5. The invention likewise relates to a mixture of at least one terpolymer as defined in claim 1 and at least one ethylene-vinyl ester copolymer. The terpolymers of the invention, and mixtures thereof, are used as paraffin inhibitors in crude oils and petroleum products.
