Notes:
A refractometric technique for determination of second-order transition temperatures (Tm) of polymers has been extended to include a series of alkyl acrylate and methacrylate polymers with transitions at temperatures down to -50°C. A convenient technique for determining refractive index down to -75°C. is described. Certain long-chain alkyl polymers are birefringent below Tm. Correlations of brittle point with Tm and relations between viscosity and Tm are reported.
