Abstract:
The invention provides polymers, methods of preparing polymers, and compositions that include polymers, wherein said polymers include a plurality of two-carbon repeating units in a polymer chain, wherein one or more of the two-carbon repeating units of the polymer chain have tertiary amine or pyridine-containing substituents; and at least about 10% of the nitrogen atoms of the tertiary amine or pyridine-containing substituents are quaternized with alkyl groups or with an alkyl group that contains one or more ethylene glycol groups. The alkyl or ethoxylated alkyl groups can also be at least partially fluorinated. The polymers can be used to provide antimicrobial surfaces and antifouling coatings.
Abstract:
A pipe or tube article comprising an innermost comprising a grafted polyolefin composition made from a grafted polyolefin composition is disclosed which can provide long lifetime, highly abrasion-resistant pipes for mining and other transportation uses. Methods for preparing the article and transporting abrasive materials through the article are also described.
Abstract:
The present invention provides compounds of formulae (I), (II), and (III), which can be block copolymers with various substituents and side-chain groups. The side-chains can include semifluorinated alkyl- and PEG-derived groups. The block copolymers can be surface active block copolymers (SABCs) and can be used as antifouling coatings. Coating compositions employing the compounds of the invention and methods for their use are also provided.
