Answer #1

Solubility parameters is mainly determined from intrinsic viscosity measurement. relation of intrinsic viscosity to polymer molecular weight and the chain-expansion factor is given by scientist flory. The chain-expansion factor can, which in turn, is mainly related to the polymer-solvent interaction parameter by correlating and using the Rory-Hug-gins theory.

A variety of models can be used to treat the interaction parameter to solubility parameters 187.102.1031: these equations have thewhich have the general form

where

is the intrinsic viscocity K is constant and is the solubility parameter

Based on matching Hildebrand Solubility Parameters (δ) as closely as possible (keep |δ solvent -δ polymer| <= 2), suggest 2 “good” solvents for each of the following polymers and 1 “poor” solvent for each. Report  values used for each polymer/solvent combination. Do not select water as a “poor” solvent.
