ABSTRACT:
The inverse emulsion polymerization of a monomer of the formula ##STR1## wherein R and R.sup.1 represent hydrogen or a C.sub.1 -C.sub.4 alkyl group, using a surfactant system having a hydrophilic-lipophilic balance value from 4 to 9, an azo-type free radical initiator and certain hydrocarbon liquids to yield a water-in-oil emulsion of a homopolymer of at least 10.sup.6 average molecular weight, the emulsion having a viscosity less than 10 cps, at 15% solids, 60 rpm Brookfield and 20.degree. C.
Also disclosed is the preparation of poly(vinylamines) of at least 10.sup.6 average molecular weight by acid or base hydrolysis of the homopolymer emulsion.
Also disclosed are cementing compositions for drilling holes containing the poly(vinylamines) and demonstrating superior properties.
