Abstract: Particles comprising a branched polymer and either a block copolymer or a linear dendritic hybrid represent a category of useful materials. They may be used in for example drug delivery applications. They may be prepared by a method comprising the steps of: dissolving the branched polymer and block copolymer or linear dendritic hybrid, and optionally other component(s), in a solvent to form a solution; adding said solution to a different liquid; and removing said solvent to form a dispersion of co-precipitated particles.

Abstract: A design painting kit having a paint roller which carries an embossed rubber-like mat upon the rotatable cylindrical surface thereof. The embossing includes design indicia and numerical indicia which signifies the color of paint to be applied to discreet areas of the design. An ink roller is removably affixed to the handle of the paint roller having the ink laden exterior surface thereof adapted to coat the embossed surfaces of the rubber mat as the rubber mat is rolled upon the surface of a wall, thereby applying an ink depiction of the pattern and numerical indicia thereto. The kit also includes a hand operated block or plate which can carry a rubber-like mat and is useful in applying the embossed indicia surfaces upon small surfaces to be decorated or upon otherwise inaccesible portions of the wall. The kit also provides a container including a supply of ink, a quantity of individually colored paints in separate containers, and a quantity of brushes.
