Abstract:

Water solution polymerization and precipitation polymerization of ethenyl radical monomers were carried out at same conditions, and the differences between the products in molecular weight and other aspects were investigated. The results indicate that the product of precipitation polymerization has a higher molecular weight and is better in the capability of inhibiting clay expansion than that of water solution polymerization.

Key words: water solution, precipitation, polymerization, molecular weight, clay expansion
