Patent

CA 2179219

- 71 - The invention provides poly(ethylene oxalate) containing recurring units represented by the following formula (1): Image (1) in a proportion of at least 60 basal mol%, wherein (a) the solution viscosity (?inh) is at least 0.25 dl/g as measured at 30°C and a polymer concentration of 0.40 g/dl in a 4:1 (by weight) mixed solvent of m- chlorophenol and 1,2,4-trichloro-benzene, (b) the melt viscosity (?*) is at least 30 Pas as measured at 190°C and a shear rate of 1,000/sec, and (c) the density is at least 1.48 g/cm3 as measured in an amorphous state, various products formed or molded from the poly(ethylene oxalate) and a production process of the poly(ethylene oxalate) The polymer is high-molecular weight and excellent in melt processability, heat resistance, crystalline properties, mechanical properties and the like, and has good degradability in soil.
