| titleOfInvention | An efficient process for the production of polyester |
| abstract | The present invention discloses an efficient process for the production of a high molecular weight polyester resin having IV of about 0.4 dl/g to about 1.2 dl/g produced from a low molecular weight crystalline prepolymer having IV of about 0.1 dl/g to about 0.4 dl/g by adding oraganotin compound at any steps during the esterification or the melt polymerization but before a particle former process which reduces dust generation in the melt polymerization and also reduces dust generation and the oligomer volatilization in the solid state polymerization. The present invention also discloses a polyester prepolymer having IV of about 0.1 dl/g to about 0.4 dl/g which is used as a precursor for solid-state polymerization. The prepolymer particles are crystalline or amorphous in nature. The prepolymer particles are cylindrical, hemispherical or spherical in shape with no sharp edges, which also helps in reducing dust generation. The present invention also provides high molecular weight polyester resin having IV of about 0.4 dl/g to about 1.2 dl/g and is used as preforms, containers, fibers or filaments, films or sheets. |
