摘要：Compositions comprising macromers having a backbone comprising units havinga 1,2-diol and/or 1,3-diol structure for tissue bulking and coating. Such polymers includepoly(vinyl alcohol) (PVA) and hydrolyzed copolymers of vinyl acetate, for example,copolymers with vinyl chloride, N-vinylpyrrolidone, etc. The backbone polymer containspendant chains bearing crosslinkable groups and, optionally, other modifiers. Whencrosslinked, the macromers form hydrogels having many properties advantageous foruse as agents to bulk and coat tissues.
