Over the past several years, TDA Research, Inc. has been developing solvent processable forms of poly(3,4-ethylenedioxythiophene) commonly known as "PEDOT". Our approach is to make block copolymers with alternating conducting and non-conducting blocks. The conducting segments provide the electronic properties, while the non-conducting segments are designed to promote dispersion. TDA has two lin...

In this study, blue-color emitting phosphors CaMgSi2O6:Eu2+ (CMS:Eu2+) were synthesized by the polymerizable complex method at 1000 °C in a reducing atmosphere. After synthesis, desired CMS crystals obtained, but small amount of impurity phases, such as Ca2MgSi2O7 and Ca3MgSi2O8, contained. By adding lithium carbonate Li2CO3 flux to washing with 1 mol dm−3 HCl solution, CMS:Eu2+ was obtained si...

With recent advances in the field of diagnostics and theranostics, liposomal technology has secured a fortified position as a potential nanocarrier. Specifically, radiation/photo-sensitive liposomes containing photo-polymerizable cross-linking lipids are intriguing as they can impart the vesicles with highly interesting properties such as response to stimulus and improved shell stability. In th...

Room-temperature ionic liquid (RTIL) has been widely investigated as a nonvolatile solvent as well as a unique liquid material because of its interesting features, e.g., negligible vapor pressure and high thermal stability. Here we report that a non-volatile polymerizable RTIL is a useful starting material for the fabrication of micro/nano-scale polymer structures with a focused-ion-beam (FIB) ...

Three hexayne derivatives with different end groups—that is, 10,12,14,16,18,20-triacontahexayne-1,30-diol (1) and its diphenylurethane (2) and diphenylester (3)—were synthesized, and their solid-state polymerization behaviors were investigated. All three monomers were thermally polymerizable. Polymers from 1 and 2 showed an absorption maximum at about 730 nm, indicating that linear polydiacetyl...

Various derivatives of vitamin A, especially esters and ethers , have been studied by many investigators. However, its macromolecular derivatives have scarcely been reported. An attempt was made by the authors to synthesize the macromo lecular derivatives of vitamin A by preparation of the polymerizable derivatives , followed by their polymerization . Thus vitamin A acrylate, methacrylate, crot...

By contrast to traditional free radical emulsion polymerization, catalytic polymerization allows for polymer microstructure control. In terms of monomers polymerizable, both techniques are largely complementary. Since the beginning of this decade, an increasing number of reports on polyolefin, polybutadiene, polyalkenamer, polynorbornene, polyketone and polyacetylene dispersions prepared by cat...
