Prediction of solubility parameter from intrinsic viscosity

Polymer for coating such as epoxy and alkyd resin use additives for enhancing physical properties, hardening acceleration, and decreasing viscosity. Therefore, diluent selection is important for blending of additives in the resin. The choice of these solvents is determined by comparing the solubility parameters. In this study, it is a measure of the intrinsic viscosity of epoxy resin by Ubbelohde viscometer and epoxy resin is calculated solubility parameter through intrinsic viscosity. The epoxy and alkyd resins’ solubility parameters were calculated from their intrinsic viscosities to be epoxy resin (δ2d=16.55δ2d=16.55, δ2p=5.98δ2p=5.98, δ2h=6.53δ2h=6.53) and alkyd resin (δ2d=19.11δ2d=19.11, δ2p=3.96δ2p=3.96, δ2h=4.86δ2h=4.86), respectively. Their total solubility parameters were calculated to be epoxy resin (δ2t=18.77δ2t=18.77) and alkyd resin (δ2t=20.11δ2t=20.11), respectively.
