This document outlines a method for determining the distribution of short-chain branching in semi-crystalline ethylene-α-olefin copolymers using differential scanning calorimetry (DSC). The technique described is applicable to various types of ethylene-α-olefin copolymers and provides guidance on sample preparation, measurement conditions, data analysis, and reporting results. It aims to offer consistent and reliable methods for assessing the short-chain branching distribution in these materials.
