Kollidon® SR is a mixture of 80% of polyvinyl acetate and 19% povidone (Kollidon® 30) in a physical mixture. Approximately 0.8% of sodium lauryl sulphate and about 0.2% of silica are used as stabilizers. It is supplied as slightly yellowish, free-flowing powder. Kollidon® SR Polymer is insoluble in water and very soluble in N-methylpyrrolidone.Polyvinyl acetate is a very plastic material
that forms a coherent matrix even under low compression forces. When the tablets are introduced into gastric or intestinal fluid, the water soluble povidone is leached out to form pores allowing the active ingredient to diffuse. Kollidon® SR does not contain ionic groups and therefore does not show interactions with drug substances.
