Chapter 6 Poly(vinyl acetate) and Related Polymers In this chapter, the family of poly(vinyl acetate) homo- and co-polymers and their derivatives are described. The important polymers are poly(vinyl acetate), poly(ethylene-co-vinyl acetate), poly(vinyl alcohol) and poly(vinyl acetal)s, including poly(vinyl formal) and poly(vinylbutyral). 6.1 Raw Materials Until the mid-60s, vinyl acetate manufacture was based almost entirely on acetylene. Since that time, however, more economical ethylene-based processes have been developed.
