POLYVINYL ACETAL WITH REDUCED FLOWABILITY

Polyvinyl acetals with a degree of acetalization of 70-84 mol %, and characterized by a molar ratio of the amount of continuous syndiotactic sequences of vinyl alcohol groups with 3 members of at least 0.152, based on the total amount of vinyl alcohol groups in the polyvinyl acetal, have exceptional...

Zusammenfassung:	Polyvinyl acetals with a degree of acetalization of 70-84 mol %, and characterized by a molar ratio of the amount of continuous syndiotactic sequences of vinyl alcohol groups with 3 members of at least 0.152, based on the total amount of vinyl alcohol groups in the polyvinyl acetal, have exceptionally low melt flow.
