Abstract
The use of aluminum sulfate as a dessicant for drying the starting materials used in polymerization reactions employing readily hydrolyzable catalysts is disclosed. The aluminum sulfate is allowed to remain in the reaction mixture during polymerization, and, indeed, may advantageously be allowed to remain in the reaction product without any deleterious effect.
