摘要：

The intrinsic brittle-ductile (craze-yield) behavior of polymers and blends are controlled by two chain parameters: entanglement density nu(e) and characteristic ratio C(infinity). These chain parameters can be predicted from chemical structure. Therefore, the intrinsic brittle-ductile behavior of polymers and blends can be controlled by chemical structure using group additivity. The chemical composition and chain structure which can give the ultimate toughness in polymers and blends are discussed.
