Room temperature curable compositions
A room temperature curable sealant/adhesive composition is disclosed. The room temperature curable sealant/adhesive composition comprises: A) one or more organopolysiloxanes; B) a hydrophilic material; C) a cross-linker; D) a titanate catalyst and/or a zirconate catalyst; and E) one or more optional ingredients. A silicone elastomer formed therefrom and related methods are also disclosed. In general, such compositions (upon several hours of contact with water) do not repel water, but rather retain and pick-up water and/or can be wetted by aqueous materials subsequent to exposure.

MICELLAR COMPOSITION FROM AN AMPHIPHILIC COPOLYMER FOR TUMOR THERAPY
An amphiphilic copolymer includes a first block, a second block and a linker covalently linking the first block with the second block, wherein the first block is a hydrophilic dendritic polyglycerol derivative having a polyglycerol backbone and carrying a plurality of sulfate or sulfonate residues substituting hydroxyl groups of the polyglycerol backbone, wherein the second block is a hydrophobic block comprising a polymer chosen from the group consisting of polycaprolactone, a polylactic acid polymer, and a copolymer of lactic acid and glycolic acid. The linker comprises a hydrocarbon having at least six consecutive methylene residues and a cleavable entity. The linker is devoid of a triazole-containing residue resulting from a reaction between an alkyne and an azide.
