Abstract
Encouraged by the results obtained in the field of graftings between polyvinyl acetate and polyvinyl alcohol, attempts were made to find factors that would bring a polyvinyl acetate emulsion to a higher content of such graftings. In this work vinyl acetate was emulsified and polymerized in water containing polyvinyl alcohol as stabilizer, potassium persulfate as catalyst, and sodium bicarbonate as a buffer. Emulsions were made, with varying degrees of hydrolysis of the polyvinyl alcohol, molecular weight, and pH during the polymerization. Paper chromatography and infrared absorption spectra were used to identify the graftings, but the results proved negative: no graftings were found.
