摘要:A process for a double stage convergent synthesis of a polymeric polyalcohol substantially and preferably built up from polyester units and composed of a monomeric or polymeric core to which at least one hyperbranched dendritic branch (dendron) consisting of a number of branching generations is added. The branching generations comprise a polymeric or monomeric branching chain extender having three reactive functions of which two are hydroxyl groups and one is a carboxyl group. The two hydroxyl groups of the branching chain extender is in a first step ketal protected by reacting said two hydroxyl groups with a ketal. A second step includes protection of the carboxyl group of said branching chain extender. The ketal protected branching chain extender and the carboxyl protected chain extender are then employed for repeated addition in a number of step yielding a predetermined number of branching generations. The thus synthesized dendron is finally added to a core having reactive hydroxyl or epoxide groups and the ketal protected hydroxyl groups are optionally deprotected.

标题:Liposome-assisted synthesis of polymeric nanoparticles
发明人：PERROTT MICHAEL G; BARRY STEPHEN E
权利人:ALNIS LLC
摘要:Synthetic polymer complements (SPCs) are provided, as well as methods for their synthesis and use. The SPCs range in size from about 20 to about 1000 nm. The SPCs have surfaces that are complementary to surface sites of target molecules, resulting in the ability of the SPCs to selectively bind to molecular targets. The molecular recognition capability of these particles enables their use in diagnostic, therapeutic, and separation applications. The SPC is formed by contacting a target template molecule with a set of building blocks solubilized in the interior of a liposome, which building blocks are then polymerized into a network to form the synthetic polymer complement in the interior of the liposome. The target templates are removed to produce complementary sites in a SPC that map the surface of the target, resulting in a water-soluble SPC nanoparticle of similar dimensions as the interior of the liposome that originally supported it and capable of molecular recognition.

标题 :Novel fluorescent pigment compositions and a process for their preparation and use of same

权利人:MALLAVARAPU LEO X
摘要:A process is disclosed for producing novel fluorescent pigment compositions with no formaldehyde or para-formaldehyde during their synthesis. The synthesis of these compositions is, for example, achieved by using an in situ reaction of epoxy resins of preferably up to a molecular weight of 20,000 with a sulfonamide compound, e.g., toluene sulfonamide, in the presence of a Lewis acid catalyst, followed by, preferably, the further reaction with an isocyanate, e.g., aliphatic isocyanate and/or para-toluene sulfonyl isocyanate. During this reaction, a fluorescent dye is incorporated into the molten mass.
