摘要
<p>A sheet made of a polyester which includes monomer units of terephthaloyl moieties, ethylene glycol moieties and isosorbide moieties is described. The polyester has an inherent viscosity of at least about 0.35 dL/g when measured as a 1% (weight/volume) solution of said polyester in o-chlorophenol at a temperature of 25 DEG C. The present invention also relates to a method of making the polyester sheet described above and a method of thermoforming the sheet into articles.</p>
