Correlations between processing characteristics and measurable physical properties were investigated for 16 commercial poly(vinyl chloride) polymers and acetate copolymers. Processing was evaluated with the Brabender Plasti-Corder. The glass transition temperature and dry blending procedure were examined by differential thermal analysis. The polymers included high and low molecular weight materials and examples of suspension, emulsion, and solution methods of polymerization. Effects due to the amount of plasticizer, stabilizers, and other additives were measured and are discussed.
