TH5890B - Purification of polyethylene terephthalate - polyoxymethylene terephthalate Polymers that promote stable release of impurities - Google Patents

Abstract

A polymer of polyethylene terephthalate-polyoxyethylene terephthalate that promotes the removal of impurities, which has been found to cause loss of properties. promoting the detachment of things Dirty when stored in contact with alkaline materials such as salts of detergent additives. for detergent synthetic organic can be stabilized by melting the poly This morph together with soluble polyacrylates and subsequently converts the molten substance. It is a solid particle which contains POT-POET, polymer and polyacryl. Let's be in a tight contact. appropriately, the molten substance is At temperatures above 70 C, i.e. within the 70 to 150 C range, the molten substance is solidified by cooling. and the resulting solid product is digested at a given temperature. Desired particle size and flake shape. Ideally, such particles pass through sieve No. 10 of the US sieve series.

Claims (1)

1.Method for making polymers of poly Ethylene Terephthalate (PET) and Polyoxymethylene Raphthalate (POET) that promotes impurities loosening, stabilizes decay and loses the loosening promoting properties when stored in the condition and loses the loosening promoting properties when stored. Are exposed to alkaline materials, such as alkaline detergent additives for detergent components. It consists of heating the polymers to melt the polymers, mixing of water-soluble polyacrylate (PA) with the molten substance, and the conversion of the molten substance. It is a solid particle containing PET-POET and PA polymers mixed (8 claims, no drawing).
