public PolymerProperties()

Method Details

calculateIntrinsicViscosity

public static double calculateIntrinsicViscosity(double K,
 double M,
 double a)

Mark-Houwink Equation. Intrinsic viscosity [eta] = K * M^a

Parameters:

K - Constant dependent on polymer/solvent/temp

M - Molecular weight

a - Scalar exponent (usually 0.5 - 0.8)

Returns:

Intrinsic viscosity

calculateTg

public static double calculateTg(double Tg_inf,
 double K,
 double Mn)

Flory-Fox equation for Glass Transition Temperature (Tg). Tg = Tg_inf - K / Mn

Parameters:

Tg_inf - Tg of infinite molecular weight polymer

K - Constant

Mn - Number average molecular weight

Returns:

Tg for the given molecular weight
