Abstract
Polymeric soil release agents that have high viscosities when molten are difficult to process. Certain organic materials can be added to such agents to lower the viscosity and improve processing. Examples of such organic materials include fatty acids, some nonionic ethylene glycol derivatives, polyethylene or polypropylene glycols and their short alkyl chain ethers, certain polyhydroxy and alkyl ether solvents, and aryl ethers of propylene glycol.
