Abstract: The present invention relates to a polyurethane polymer comprising as part of its polymer backbone an ?-oxy carbonyl moiety of general formula (I), where A and B represent the remainder of the polymer backbone and are the same or different, and R is an optionally substituted aliphatic hydrocarbon having three or more carbon atoms.

Abstract: The present invention relates generally to new surfaces for solid phase chemistry applications, more specifically plastics surfaces modified by graft polymerisation for use in chemical synthesis and/or immobilisation of chemical entities and/or compounds.

Abstract: New surfaces for solid phase chemistry applications are disclosed, specifically plastics surfaces modified by graft polymerization for use in chemical synthesis and/or immobilization of chemical entities and/or compounds. In particular, an activated modular grafted polymeric surface is disclosed which is suitable for use as a reagent for solid phase organic synthesis, or as a reagent for the affinity capture, presentation or preparation of biomolecules such as proteins, oligonucleotides, nucleic acids, peptides, and lectins. The grafted polymeric surfaces are particularly useful as scavenger reagents in combinatorial synthetic protocols, and as affinity reagents in protein purification and proteomics.
