Biodegradable polymers with sulfenamide bonds for drug delivery applications

The present invention provides novel, modified polydicyclopentadienes and methods to prepare modified polydicyclopentadienes. The modified polydicyclopentadienes prepared by the methods of the invention are useful in many applications including new and useful solid phases for chromatography.

Modified polydicyclopentadienes

The invention provides a method of contacting a membrane having a highly cross-linked polydicyclopentadiene matrix with a feed solution having a) a first component with a molecular weight in the range of from about 100 g molto about 600 g moland a cross-sectional area of less than about 0.40 nmand b) a second component with a molecular weight in the range of from about 100 to about 600 grams g moland a cross-sectional area of greater than about 0.50 nmso that the feed solution is fractionated into a permeate comprising the first component and a retentate enriched in the second component.

High-density polydicyclopentadiene

The invention provides methods and an apparatus useful for site-isolating reagents or catalysts during chemical reactions. The methods and apparatus are useful for carrying out cascade or domino reactions.
