Résumé

This document specifies a test method for the estimation of the short chain branching distribution of semicrystalline ethylene 1-olefin copolymers by successive self-nucleation and annealing (SSA) with conventional, high performance and fast differential scanning calorimetry.

This document is applicable to the estimation of the short chain branching distribution of raw materials of semicrystalline ethylene 1-olefin copolymers and its products.

Quantitative calculation of short chain branching content, degree of crystallinity and short chain branching distribution is applicable to ethylene/1-butene copolymers, ethylene/1-hexene copolymers and ethylene/1-octene copolymers.
