Abstract
Improved halogenation techniques for poly(1, 4-butadiene) have made well-defined head to head poly(vinyl chloride) and head to head poly(vinyl bromide) accessible in larger quantities. This allowed the preparation and study of blends of poly(vinyl chloride) or poly(vinyl bromide) with polycaprolactone and poly(methyl methacrylate); blends were also prepared between the poly(vinyl halides). The thermal behavior and the thermal degradation behavior of these blends were investigated. It was confirmed that head to head and head to tail poly(vinyl chloride) are immiscible over almost the entire range of compositions.
