  • Patent number: 8574669
    Abstract: A fine polymer particle production method includes producing an emulsion in a liquid prepared by dissolving and mixing a polymer A and a polymer B in organic solvents in which a solution phase composed primarily of the polymer A and a solution phase composed primarily of the polymer B are formed as separate phases, and bringing it into contact with a poor solvent for the polymer A to precipitate the polymer A. This method serves for easy synthesis of fine polymer particles with a narrow particle size distribution and the method can be effectively applied to production of highly heat-resistant polymers that have been difficult to produce with the conventional methods.

  • Patent number: 6924315
    Abstract: The present invention provides compounds useful as surfactants having formula (1), including isomers thereof: wherein a and b are integers independently selected from about 3 to about 6; x is an integer from about 1 to about 12; (m+n) is from about 1 to about 4; the R1 groups are independently selected from the group consisting of linear, cyclic, and branched alkyl, alkenyl, aryl, and alkylaryl groups having from about C3 to about C30 atoms; and when (m+n) is equal to or greater than 2, each R1 may be independently R2 or R3, wherein R2 and R3 are independently selected from the group consisting of linear, cyclic, and branched alkyl, alkenyl, aryl, and alkylaryl groups having from about C3 to about C30 atoms. The invention also provides a method for reducing surface tension in a waterborne composition or an industrial process by the incorporation of a surfactant having formula (1) and an aqueous composition comprising a surfactant having formula (1).

  • Patent number: 6673359
    Abstract: The present invention teaches the composition of terminally modified, amino, polyether, siloxanes, known henceforth as amino siloxane alkokylates, and their use as adjuvants. The amino siloxane alkoxylates of the present invention enhance the efficacy of agrichemicals on plants as compared to conventional TSE's alone. The amino siloxane alkoxylates have at one end, an amine functionality and at the other end, a polyalkyleneoxide functionality.

  • Patent number: 6569358
    Abstract: The method of preparing the porous material incorporating ultrafine metal particles comprises the following steps: (1) preparing surface-protected ultrafine metal particles by reducing metal ions in the presence of molecules such as dodecanethiol molecules; (2) immersing a wet gel in a solution of the ultrafine metal particles, thus forming an ultrafine metal particle/wet gel composite in which the ultrafine metal particles are incorporated in the wet gel; and (3) drying the ultrafine metal particle/wet gel composite to form a porous body.
