20110003154 | ENCAPSULATED MORDANT PARTICLE DISPERSION AND METHOD OF PREPARING - The present invention discloses a method of making core-shell polymer particles, comprising forming a linking-group-containing polymer by derivatizing a hydroxy-group-containing polymer, comprising hydroxy groups on adjacent carbon atoms with a linking agent, that is a compound comprising both an aldehyde moiety and an amine moiety, wherein one or more acetal moieties are formed in the linking-group-containing polymer, each acetal formed by the reaction of the aldehyde moiety in the linking agent with two hydroxy groups in the linking-group-containing polymer, wherein the amine moiety then becomes a linking group pendent from the linking-group-containing polymer, wherein the linking group is capable of reacting with a precursor group in the precursor polymer. Also disclosed are compositions comprising insoluble core-shell particles made by the method. | 01-06-2011 |

20080269444 | PEG-Substituted Pyridine Ligands and Related Water-Soluble Catalysts - Amphiphilic Group VIII metathesis catalysts, as can be used in a range of polymerization reactions and other chemical methodologies. | 10-30-2008 |
20090275782 | Quantum Dots Tailored with Electronically-Active Polymers - Cadmium selenide, and other quantum dot materials, can be integrated into thin films of poly(para-phenylene vinylene) (PPV) or other polymer compounds without aggregation of the nanocrystals. Solid-state photoluminescence spectra of composite materials prepared by these novel techniques reveal the effect of this greatly enhanced quantum dot-polymer interface relative to cases where the nanoparticles are aggregated, such that electronic communication and energy transfer between the nanoparticle and polymer components is made more efficient. | 11-05-2009 |
20100036061 | Amphiphilic Polymer Capsules and Related Methods of Interfacial Assembly - Polymer capsules from amphiphilic graft copolymers comprising reactive, hydrophobic polyolefin backbones, and hydrophilic poly(ethylene glycol) (PEG) grafts are produced by self-assembly of the polymers at the oil-water interface, and crosslinking the assembly with bis-cyclooctene PEG derivatives in conjunction with ring-open metathesis polymerization catalysts. The use of the graft copolymer architecture in capsule synthesis provides significant opportunities to tune both the surface properties, in terms of recognition, and the membrane properties, in terms of mechanical strength, encapsulation, and release. | 02-11-2010 |
