Determination of molecular weight of polymers by viscosity method.

Determination of molecular weight of polymers by viscosity method. It is a simple method for determining the molecular weight of polymers. Addition of polymers in the solvent increases the viscosity of the solvent, due to introduction of inhomogeneities by the polymers. If η₀ is the viscosity of the solvent and η is the viscosity of the solution at the same temperature, then the relative viscosity is given by Relative viscosity. Specific viscosity:  It is defined as the relative increase in viscosity and is given as Specific viscosity. Reduced viscosity: It is defined as the relative increase in viscosity per unit concentration (C) of polymer and is given as Reduced viscosity. Intrinsic viscosity: The reduced viscosity is dependent on concentration (C). If a graph is plotted between  reduced viscosity vs concentration then the extraplotation value when C=0 is called intrinsic viscosity. Intrinsic viscosity. Graph of reduced viscosity vs concentr

Determination of molecular weight by Light scattering method.

Determination of molecular weight by Light scattering method. Due to big size macromolecules in solution, turbidity is produced. The light rays get scattered, when pass through macromolecule solution due to turbidity. The turbidity T is given by Where I₀ is the intensity of incident light. Iₜ is the intensity of transmitted light after passing through a solution of length l.        In case of proteins or higher polymers the turbidity is small and is determine from the intensity of light scattered at 90° to the beam. This can be done by using a simple photometer as shown in figure below. Turbidity increase with increase in concentration as well as molecular weight. The Turbidity is related to molecular weight by the equation given by Debye. Hc/T=1/M+2Bc Where B is second virial coefficient and H is a constant. If we plot a graph between Hc/T vs c we get a straight line with intercept 1/M. Thus This curve was plotted by Zimm, so is called Zimm's Curve. Thus the c

Fibre Reinforced Polymer.

Fibre Reinforced Polymer; Fibre reinforced polymer are also called fibre reinforced plastic. A composite is a combination of two or more materials which differ in form or composition on a macroscale . Fibre reinforced polymer (FRP) is a composite that consist of high performance fibres embedded in a polymer matrix. Fibres utilized in FRP are carbon, glass and aramid. Polymers utilized in FRP are epoxy, vinyl ester, polyester and phenol formaldehyde resins. Fibre reinforced composites can have different arrangement of fibres within the polymer. (a) One dimensional arrangement;  Here the fibres are only aligned in X-direction. (b) Two dimensional arrangement, random; Here the fibres are randomly aligned in X-direction and Y-direction. (c) Two dimensional arrangement, oriented; Here the fibres are aligned in X-direction and Y-direction in a particular manner. (d) Three dimensional arrangement, random; Here the fibres are randomly aligned in X-direction, Y-dire
