The apparent viscocity of polymer melt of PET/CDP and PET/ECDP is increased with the increasing of amount of CDPand ECDP added , the apparent viscocity of polymermelt of PET/CGP is decreased with the increasing of amount of CGP added.

• PET/CDP和PET/ECDP熔体的表观粘度随着添加CDP和ECDP增加而增大； 而PET/CGP熔体的表观粘度随着CGP含量增加而降低。
