    Abstract: A blend is provided, which includes 50 to 99 parts by weight of PET and 1 to 50 parts by weight of modified PEF. The modified PEF is polymerized of diacid, ester of diacid, or a combination thereof and polyol. The diacid, ester of diacid, or a combination thereof includes (1) furan dicarboxylic acid, dialkyl furandicarboxylate, or a combination thereof or (2) furan dicarboxylic acid, dialkyl furandicarboxylate, or a combination thereof and spiro-diacid. The polyol includes (3) C2-C14 polyol or (4) C2-C14 polyol and spiro-diol. The diacid, ester of diacid, or a combination thereof includes (1) furan dicarboxylic acid, dialkyl furandicarboxylate, or a combination thereof, the polyol includes 1 to 3 parts by mole of (4) C2-C14 polyol and spiro-diol, wherein the spiro-diol and the furan dicarboxylic acid, dialkyl furandicarboxylate, or a combination thereof have a weight ratio of 500 ppm to 4000 ppm.
