The obtained polymers may be used for separation of enantiomers, diastereomers of the template molecule, and also for separation of the template molecule or template molecule analogues from structurally related compounds.Type: GrantFiled: November 15, 2006Date of Patent: February 19, 2008Assignee: MIP Technologies ABInventors: Börje Sellergren, Andrew Hall, Karine Chenon, Rohini Karmalkar

Patent number: 7268189Abstract: The invention relates to novel crosslinkable copolymers which are obtainable by (a) copolymerizing at least one hydrophilic monomer having one ethylenically unsaturated double bond and at least one crosslinker comprising two or more ethylenically unsaturated double bonds in the presence of a chain transfer agent having a functional group; and (b) reacting one or more functional groups of the resulting copolymer with an organic compound having an ethylenically unsaturated group. The crosslinkable copolymers of the invention are especially useful for the manufacture of biomedical mouldings, for example ophthalmic mouldings such as in particular contact lenses.Type: GrantFiled: March 21, 2006Date of Patent: September 11, 2007Assignee: Novartis AGInventors: Beat Müller, Alain Laurent, Veerle Coessens, Aaldert Rens Molenberg
