    摘要: Polyester blends comprising (1) polyesters prepared from terephthalic acid, 100 to 5 mol% of 2,2,4,4-tetramethyl-1,3-cyclobutanediol, and 0 to 95 mol% 1,4-cyclohexanedimethanol and (b) polyesters prepared from terephthalic acid and alkylene glycol. The blends may also contain an impact modifier and a phosphorous stabilizer. These blends can have a combination of thermal stability and toughness — making the materials useful in engineering molding plastics, packaging, films, and fibers.
