Patent ID: 8849583

Claim:
A method for analyzing side chains of a polymer, the method comprising the steps of: 1) displaying a log scale graph of the molecular weight and the intrinsic viscosity of a polymer; 2) calculating an explanatory power (R 2 ) value of a regression equation between a coordinate closest to an origin and a coordinate farthest from the origin or a coordinate closer to the origin than the coordinate farthest from the origin, among the total coordinates of the graph, and determining whether the value exceeds a previously set reference explanatory power (R 2 ) value of a regression equation; and 3) computing a critical point representing a maximum straight-line segment using the calculated explanatory power (R 2 ) value of the regression equation, if the calculated explanatory power (R 2 ) value of the regression equation exceeds the previously set reference explanatory power (R 2 ) value of the regression equation.
