초록

An improved granulation and tablet product for water treatment. One or more water treating agents are dispersed and entrapped in a water soluble polymeric material which is more water soluble than the water treating agent. The water treating agent is entrapped in a polymeric matrix by first treating the polymeric material with an alcohol, blending with the water treating agent and subsequently adding water to the admixed polymeric material and water treating agent.

청구항

A granulation or tablet product wherein a dry ingredient is entrapped in a polymeric material, the dry ingredient being different from the polymeric material and being less water soluble, said product produced by the steps comprising: treating said polymeric material with an alcohol which is substantially free of water to blanket said polymeric material from moisture and air; admixing said alcohol treated polymeric material with said dry ingredient; and combining said admixed product with water to bond the polymeric molecules of said polymeric material t...
