| titleOfInvention | Flame retardant polyethylene terephthalate masterbatch and process of making thereof |
| abstract | The present invention relates to a method of preparing a polyester masterbatch composition with reactive phosphorus based additive comprising (a) preparing oligomers or pre-polymers comprising one or more monomers; (b) reacting the said oligomers, the said pre-polymers, and unreacted monomers with one or more additives and one or more phosphorus (P) based flame retardant additive so as to achieve up to 60,000 PPM phosphorus (P) in final reaction product, wherein the at least one phosphorus based flame retardant additive is Carboxyalkyl(phenyl) phosphinic acid; (c) melt polymerizing the said reaction product to obtain amorphous polyester, and further crystallizing the said amorphous polyester in a rotary or fluid bed crystalizer; and (d) subsequently, subjecting the said crystalized amorphous polyester chips of lower I.V. to solid state polymerization in batch or continuous solid state polymerizer to obtain the said polyester masterbatch of high intrinsic viscosity |
