  • Publication number: 20110024699
    Abstract: A polymeric polymer containing poly(oxyethylene)-amine and its application to preparation of silver nanoparticles. The polymeric polymer is prepared from poly(oxyethylene)-amine and a linker, for example, poly(styrene-co-maleic anhydride) (SMA) or dianhydride. The polymeric polymer can chelate silver ions and reduce them to silver atoms which are dispersed as nanoparticles. No additional reducing agent is needed and more than 30% of solid content of the nanoparticles solution can be achieved without aggregation. The prepared silver nanoparticles are both hydrophilic and hydrophobic and therefore are compatible with polymers.

  • Patent number: 7745561
    Abstract: The invention provides alternatives to traditional polycondensation processes for preparing copolymers. For example, in certain embodiments, the invention provides a process that includes an extrusion step and a solid state polymerization step to prepare high molecular weight block copolymer with a “hard block” contributed by a macrocyclic polyester oligomer (MPO) and a “soft block” contributed by a dihydroxyl-functionalized polymer, an oligoether, and/or a dimerized fatty acid (i.e. a polyol). The invention also provides new copolymer compositions made possible by the new processes—for example, copolymers of higher molecular weight, copolymers with higher weight ratio of soft block units to hard block units, copolymers made with higher molecular weight polyol, and copolymers with hard block units that are themselves random copolyesters of units contributed by a MPO and a cyclic ester.
