Poly PVAC

More than 500 million pounds of poly(vinyl acetate) (PVAc), poly(vinylidene chloride), and their copolymers and polymers derived from them are produced annually in the United States. PVAc does not have sufficient strength for producing the types of products obtained from polyethylene, polystyrene, and poly(vinyl chloride) since it is noncrystalline and has a Tg of only 28°C. However, poly(vinyl acetate) (XLI) and its copolymers find uses as... [Pg.306]

From Table I it is clear that polystyrene (PS) and polyethylene terephthalate (PET) are much more resistant to y-rays than polypropylene (PP), low density PE (LDPE), poly(oxymethylene) (POM), poly(vinyl acetate) (PVAc), poly(propylene oxide) (PPOx), and somewhat more resistant than poly(methyl methacrylate) (PMMA) or 6-6 nylon. A very commonly used plastic, poly(vinyl chloride) (PVG), is perhaps the least resistant of all the plastics giving off hydrogen chloride with quite a high G-value when irradiated. [Pg.18]
