Vinylacetat-Vinylalkoholcopolymere, Verfahren zur Herstellung und Verwendung davon

摘要

Vinyl acetate/vinyl alcohol copolymer, having an average degree of polymerization between 150 and 1500, containing between 5% and 10% of oligomers with a degree of polymerization between 5 and 30, and having an average length of the blocks of the vinyl alcohol groups between 8 and 12 units. Process for the production of said vinyl acetate/vinyl alcohol copolymer and use thereof in the suspension polymerization of vinyl chloride polymers and copolymers, substantially exempt from closed cells.
