Webthe primary result of entanglements in high molecular weight polymers is the constraining of a test chain to longitudinalmotion along its own contour. The following books have been very helpful in the preparation of these lec-tures: • W.J. Briels, Theory of Polymer Dynamics, Lecture Notes, Uppsala (1994). WebPolymer Crystals (cont.) Polymers rarely 100% crystalline • Difficult for all regions of all chains to become aligned • Degree of crystallinity expressed as % crystallinity.--Some physical properties depend on % crystallinity.--Heat treating causes crystalline regions to grow and % crystallinity to increase.
