TH3754EX - Purification of polyethylene terephthalate - polyoxymethylene terephthalate Polymers that promote stable release of impurities - Google Patents

Abstract

Polyethylene terephthalate-polyoxyethylene terephthalate polymers that promote the release of impurities, which have been found to lose their properties. Promoting the detachment of things Dirty when stored under conditions in contact with alkaline materials such as salts of detergent additives. For detergent Synthetic organic It can be stabilized by fusing poly This mortar, together with soluble polyacrylate, and subsequently transforms the molten substance. It is a solid particle containing POT-POET, polymer and polyacrylate. Let it be in a state of close contact. Appropriately, the molten substance is At temperatures above 70 ° C, for example, within the range 70 to 150 ° C, the molten material is solidified by cooling. And the resulting solid product will be digested at a given temperature Ideally, the particles are then passed through the sieve number 10 of the US sieve series.
