Polyethylene and polypropylene are semi crystalline polymers and this booklet discusses how the molecules form into amorphous and crystalline regions such as lamellae and spherulites. Determination of the degree of crystallinity from DSC and density column is considered. The DSC technique is described and the form of the melting and crystallization curves discussed. Finally examples of micrographs obtained from optical, scanning electron and transmission microscopy are given.
