Abstract

disclosed is a process for preparing containers, such as bottles, using a branched polyester of terephthalic acid, a combination of ethylene glycol and 1,4-cyclohexanedimethanol and a small amount of a polyfunctional branching compound. A molten parison of such polyester is extruded and then expanded in a container mold to form the desired container.
