ABSTRACT:
Disclosed in this invention are copolymers containing about 0.5% to about 20%, by weight, of a C.sub.10 -C.sub.36 monoepoxide and about 99.5% to about 80%, by weight, of a 1,3 dioxolane. These copolymers are useful in increasing the viscosity of aqueous systems employed in various end uses, such as coatings and hydraulic fluids.
