| titleOfInvention | Process for making thermoplastic profiles having reduced melt fracture |
| abstract | In a process for producing a profile by profile extrusion of a thermoplastic resin, a melt of the thermoplastic resin is extruded through a die to form the profile. The process is improved by utilizing a thermoplastic resin having a composition of from about 99.95 to about 98.0 weight percent amorphous or semicrystalline polyester and from about 0.05 to about 2.0 weight percent of a zinc salt of an organic acid. The improvement of the process is either by increasing speed or decreasing temperature of a profile extrusion process already operating at a maximum speed and/or temperature with experiencing melt fracture. When melt fracture is present in the profile extrusion process, a method for reducing melt fracture in a profile is accomplished by combining from about 99.95 to about 98.0 weight percent amorphous or semicrystalline polyester and from about 0.05 to about 2.0 weight percent of a zinc salt of an organic acid to form a melt, extruding the melt through an orifice of a die at a temperature and a speed to form an extruded article having a shape, and thereafter quenching the extruded article to form a profile. |
