Abstract: Side-chain crystallizable (SCC) polymers are useful in various medical applications. In certain applications, heavy atom containing side-chain crystallizable polymers (HACSCCP's) are particularly useful. An example of a HACSCCP is a polymer that comprises a main chain, a plurality of crystallizable side chains, and a plurality of heavy atoms attached to the polymer. In certain configurations, the heavy atoms are present in an amount that is effective to render the polymer radiopaque. A polymeric material that includes an HACSCCP may be fabricated into a medical device useful for at least partially occluding a body cavity. For example, such a medical device may be an embolotherapy product. A polymeric material that includes a SCC polymer may also be fabricated into other medical devices, such as stents.

Abstract: A mill base composition includes a compound comprising a divinyl ester of a dicarboxylic acid, a dispersing agent, and a pigment. The divinyl ester of the carboxylic acid includes from 2 to about 8 carbon atoms. The mill base composition is subjected to milling with milling beads to produce a milled mill base composition that functions as a pigment concentrate that may be added to an ink vehicle to form an ink composition suitable for use in inkjet ink devices. The milled mill base composition is particularly suited for UV curable ink compositions. A UV curable ink composition includes the pigment concentrate, one or more UV curable monomers, and one or more UV initiators.

Abstract: Methods are described for activating a glass fiber or flake to participate in polymerizing a resin. The methods may include sizing the glass fiber or flake with a sizing composition that includes a solution containing a polymerization initiator, and activating the polymerization initiator by forming a free radical moiety on the polymerization initiator that can initiate the polymerization of the resin. Additional methods of making a glass reinforced composite are described. The methods may include sizing glass fibers or flakes with a sizing composition that includes a solution containing a polymerization initiator, forming a free radical moiety on the polymerization initiator to make activated glass fibers or flakes, and contacting the activated glass fibers or flakes with a polymer resin. The activated glass fibers or flakes initiate the polymerization of the resin around the glass fibers or flakes to form the glass reinforced composite.
