摘要 |
Polyethylene terephthalate-polyoxyethylene terephthalate soil release promoting polymers, which have been found to be subject to loss of soil release promoting properties on storage in contact with alkaline material, such as builder salts for synthetic organic detergents, are stabilized by melting them together with a water soluble polyacrylate and subsequently converting the melt to solid particles which contain the PET-POET polymer and polyacrylate in intimate contact. Preferably the melt is at a temperature above 70 DEG C., such as within the range of 70 DEG to 150 DEG C., the melt is solidified by cooling and the solid product resulting is cryogenically size reduced to desired particle size and flake shape, preferably such as will pass through a No. 10 sieve, U.S. Sieve Series. |
