  • Publication number: 20200306183
    Abstract: The present invention relates to a polymer composite for controlled release of an agent. In particular, the present invention relates to a stimuli-responsive polymer composite that can provide for controlled release of an agent in response to light. The polymer composite may be particularly suitable for the controlled delivery of a drug that is modulated by light.

  • Publication number: 20200280095
    Abstract: An electrolyte composition comprising (i) a block copolymer, (ii) an organic electrolyte (e.g. an ionic liquid), and (iii) a lithium salt, wherein the block copolymer comprises a non-ionic block and an ionic block, the non-ionic block comprising polymerised residues of hydrophobic monomers, and the ionic block comprising polymerised monomer residues having covalently coupled thereto (a) a pendant organic ionic liquid cation, the pendant organic ionic liquid cation having a counter anion, (b) a pendant anionic moiety, the pendant anionic moiety having a counter cation, or (c) a combination thereof, and the electrolyte composition has at least two glass transition temperature (Tg) values.

  • Publication number: 20190358341
    Abstract: The present invention provides a biocompatible and hydrophilic polymer conjugate comprising a linear, aliphatic copolymer backbone to which is conjugated a binding moiety and an agent. The binding moiety is conjugated to an end of the copolymer backbone and facilitates targeted delivery of the agent. Also provided are methods for preparing such polymer conjugates via free radical polymerisation techniques such as reversible addition fragmentation chain transfer (RAFT) polymerisation and uses of such polymer conjugates in diagnosis or therapy.

  • Publication number: 20110190467
    Abstract: The present invention relates to a macromonomer having a polydimethylsiloxane backbone that has a mol % dimethyl siloxanes, b mol % siloxanes substituted with -K-RIM, c mol % siloxanes substituted with -K-RIM-Z and d mol % siloxanes substituted with -L-Z, and in which the terminal siloxane groups are tri-substituted with R, wherein RIM is a refractive index modifying group; Z is a free radically polymerisable group; K is a spacer group; L is optional and is a spacer group; each R is independently selected from an RIM, a lower alkyl group, hydrogen or Z; and a is a molar percentage of the macromonomer which is in the range of from 0 to 95 mol %; b is a molar percentage of the macromonomer which is in the range of from 5 to 99 mol %; c is a molar percentage of the macromonomer which is in the range of from 0 to 2 mol %; and d is a molar percentage of the macromonomer which is in the range of from 0 to 2 mol %; with the proviso that c and d are not both 0 mol %.
