Title:
PRODUCTION OF WATER-SOLUBLE VINYL SUGAR POLYMER
Document Type and Number:
Japanese Patent JPS61103909
Kind Code:
A
Abstract:
This invention provides a process for the preparation of water-soluble vinyl saccharide polymers by polymerisation of at least one water-soluble monovinyl saccharide monomer in water at a temperature in the range of from 10 °C to 90 °C, characterized in that the polymerisation is carried out in the presence of an azo-type free-radical initiator and that the concentration of water-soluble monovinyl saccharide monomer in water is not higher than 150 kg/m3. The polymers prepared according to the invention may advantageously be used for EOR and for water treatment.
