Abstract: The present application relates to a method for quantitative analysis of a polymer structure. Specifically, the method may be carried out through steps of measuring rheological properties and/or molecular weight distribution of the arbitrarily selected polymer, setting a random value for the selected polymer and then predicting the rheological property and/or the molecular weight distribution of the polymer from the random value, and comparing the measured value with the predicted value to determine the value of the structural parameter of the polymer.

Abstract: The low density polyethylene copolymer according to the present invention is characterized in that as LCB (Long Chain Branch) is introduced into LLDPE, the melt strength is remarkably high even without blending with LDPE, and thus it can be advantageously applied to blown film processing and the like.
