Melt viscosity depressant for polyester resin and polyester resin composition comprising the same |
摘要 |
A new melt viscosity depressant for a polyester resin having a structure of an aromatic carbonyl compound is disclosed. Addition of the melt viscosity depressant to a polyester resin reduces the melt viscosity of the resin remarkably, thereby facilitating mold processing and melt-spinning of the polyester resin composition, from which high strength polyester molding products and polyester fibers can be obtained.
