Restaurant smallware comprising polyester compositions formed from 2,2,4,4-tetramethyl-1,3-cyclobutanediol and 1,4-cyclohexanedimethanol
摘要:
Described are restaurant smallware, comprising polyester based composition, comprising dicarboxylic acid component as terephthalic acid residues and optionally, aromatic dicarboxylic acid residues or aliphatic dicarboxylic acid residues and glycol component, comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol residues and cyclohexanedimethanol residues. The polyester composition has the inherent viscosity from 0.55 to 0.0.68 dL/g as determined in 60/40 (wt/wt) phenol/tetrachloroethane at a concentration of 0.5 g/100 ml at 25° C., glass transition temperature Tg of 110° C. to 160° C., notched Izod impact strength of at least 7.5 ft-lb/inch at 23° C. according to ASTM D256 with a 10-mil notch in a ⅛-inch thick bar, melt viscosity is less than 10,000 poise as measured at 1 radian/second on a rotary melt rheometer at 290° C. and does not contain polycarbonate.
