Molecular WeightMn = XnMo + Meg

PDI = Mw/Mn

Mark-Houwink-Sakurada equation: [] = KMva

Einstein Guth Equation:

Mn(polyA + polyB) = fAMn(polyA) + fBMn(polyB)Mw(polyA + polyB) = wAMw(polyA) + wBMw(polyB)Ebullioscopy: Tb = KbmCryoscopy: Tf = Kfm With m = molality (moles of solute/kg of solvent)Vapor Pressure Depression: P = XAPSo PSo = vapour pressure of solvent

Membrane Osmometry:

Light Scattering: Diffusion: A + B (A B)A-B kRkDkD

The rate of reaction : Condensation Polymerization

Self catalyzed: acid catalyzed:

A-A with excess of BB:

(A-A + B-B + B) or (A-B + B):

Radical Chain Polymerization

Ri = 2fkd[I]Rp = kp[M][M]Rt = 2kt[M]2
