More Information
Summary:A process for the preparation of flaked or pelletized or granulated non-ionic or anionic homo- or copolymers of polyethyleneterephthalate (PET) and/or polyoxyethyleneterephthalate (POET) comprises heating such polymer to melt it, mixing the molten polymer with a powdered organic or inorganic substrate, allowing the mixture to solidify whereby the polymer and the powdered organic or inorganic substrate stay in intimate contact and converting the solid formed by any suitable particle reducing process into flakes or pellets or granules. The products are in particular useful as soil release agents in laundry and fabric care products.
