20110158910 | MICROPARTICLES COMPRISING POLYMERS WITH THIOESTER BONDS - The present invention relates to particles suitable for delivery of active agents comprising a polymer containing thioester bonds which are obtained via the reaction of a thioic acid functionality and an unsaturated group. The polymer may be is linear, branched or crosslinked. The particles have an average diameter in the range of 10 nm to 1000 μm, preferably in the range of 100 nm-100 μm. The particles may comprise an active agent selected from the group of nutrients, pharmaceuticals, proteins and peptides, vaccines, genetic materials, diagnostic agents or imaging agents. The present invention further relates to the use of the particles in dermatology, muscular skeletal, oncology, in vascular applications, in orthopaedics, in ophthamology, spinal, intestinal, pulmonary, nasal, or auricular. | 06-30-2011 |
20110223206 | MICELLE COMPOSITIONS AND PROCESS FOR THE PREPARATION THEREOF - The present invention relates to a micelle composition comprising a hydrophobic compound and an amphiphilic block copolymer, wherein the amphiphilic block copolymer consists of a hydrophobic block A and a hydrophilic block B, the hydrophobic block A comprises at least one hydrophobic polymeric unit X and the hydrophilic block B comprises at least one hydrophilic polymeric unit Y whereby the X and Y blocks alternate. | 09-15-2011 |
20130102687 | MICELLE COMPOSITIONS AND PROCESS FOR THE PREPARATION THEREOF - The present invention relates to a micelle composition comprising a hydrophobic compound and an amphiphilic block copolymer, wherein the amphiphilic block copolymer consists of a hydrophobic block A and a hydrophilic block B, the hydrophobic block A comprises at least one hydrophobic polymeric unit X and the hydrophilic block B comprises at least one hydrophilic polymeric unit Y whereby the X and Y blocks alternate. The present invention further relates to a process for the preparation of the micelle composition wherein the process comprises the steps of: a) dissolving the hydrophobic compound and the amphiphilic block copolymer in an organic solvent to form a solution, b) adding said organic solution into an aqueous medium, c) optionally repeating aforementioned steps. The micelle composition according to the present invention is useful in medical applications such as therapeutic cardiovascular applications, veterinary applications, food processing applications, flame retardant applications, coatings, adhesives and cosmetics, fabric/textiles, industrial and art applications. | 04-25-2013 |
