高分子材料のIzod衝撃強さと高分子構造

抄録

Izod impact strength is examined in respect of its relation to chemical structures. Entanglement density and the characteristic ratio of the mean square end-to-end distance of a actual polymer against to that of an idealized freely joined chain (C_∞) are used, as parameters representing the chemical structure of the polymers. A functional relation is found between the Izod impact strength and the ratio of the entanglement to C_∞. A method for predicting the Izod impact strength from the chemical structure of the polymer is reported.
