## Abstract The use of weak alkalies such as sodium carbonate (Na~2~CO~3~), sodium bicarbonate (NaHCO~3~) and their 1 : 1 molar mixture, and strong alkalies such as sodium hydroxide (NaOH) and sodium methoxide (NaOMe) as pH controllers in suspension polymerization of vinyl acetate monomer (VAM) has

Copolymers of vinyl chloride-vinyl acetate have been prepared with different vinyl acetate contents and molecular weights and under different polymerization conditions. A rheological study of these copolymers indicates that they behave in some ways like externally plasticized PVC. For instance, as t
Three di β erent emulsiΓer types from vinyl acetate monomer and methoxypolyoxyethylene (35 : 65, 27 : 73 and 19 : 81 wt : wt%) were prepared in the presence of benzoyl peroxide using a macroradical initiator technique. Fourier transform infrared spectroscopy and 1H nuclear magnetic resonance were car
## Abstract It is a common view that poly(vinyl acetate) has many branches at the acetyl side group, but that the corresponding poly(vinyl alcohol) has little branching. In order to study the branching in poly(vinyl acetate) and poly(vinyl alcohol) which is formed by chain transfer to polymer, the
