This handbook covers the basics of specimen preparation, the microstructure of semi-crystalline polymers, blends, and composites, and methods for the study of polymer surfaces. The coverage is generally qualitative rather than quantitative, except for that on birefringence measurements of orientation effects. The text emphasizes those methods which are likely to lead to success in relation to specific types of problems. The treatment is highly practical and intended to aid those who are inexperienced in the microscopy of synthetic polymers to utilize their microscope to the greatest effect. -- AATA
