Refractometric determination of second‐order transition temperatures in polymers. II. Some acrylic, vinyl halide, and styrene polymers

摘要: A refractometric method for determination of second-order transition temperatures polymers has been extended to include a series which the occurs between 0° and 75°C. Refractive index data within ±30° 50°C. temperature are given some acrylate, methacrylate, vinyl chloride, vinylidene styrene copolymers. These show discontinuities locate these polymers. Deviation from linear relation near Tm related time effect.
