Abstract:
A method of manufacturing a molded article by a low shear manufacturing process that includes: placing a solid polyester in a mold having mold surfaces; heating said polyester until it becomes molten; dispersing said molten polyester over said mold surfaces; solidifying said molten polyester to form a solid molded article; and removing said molded article from said mold; where the polyester is obtained by polymerization of dimethylcyclohexane dicarboxylic acid, cyclohexane dimethanol, polytetramethylene ether glycol and branching agent and has a steep melting curve evidenced by a puddling curve slope of −2 to −10.
