Describes two methods for evaluating the melting behaviour of semi-crystalline polymers. Method A - Capillary tube - This method is based on the changes in shape of the polymer and is applicable to all semi-crystalline polymers and their compounds. Method B - Polarizing microscope - This method is based on changes in the optical properties of the polymer and is applicable to polymers containing a birefringent crystalline phase.
