a new linear relation between mole-cular weight and flow temperature is proposed
In M = AE/RTf.With fractionatedpolymethylmethacrylate as testing sample
both cold-molded and hot-molded
the experimental results are in accord with the above relation under different loading conditions. The effects of sample molding and loading weight on the temperature-deformation properties are discussed.
