摘要：
Articles such as catheters or balloons that have an ester-linked poly(ester-block-amide) substrate have a lubricious hydrogel coating which suppresses particle development under accelerated aging conditions. A polymerizable coating composition is applied to the substrate without application of an intervening primer layer and cured. The coating composition comprises an uncrosslinked polyvinylpyrrolidone polymer that is free of attached photoinitiator groups and at least one polyfunctional ethylenically unsaturated monomer.
