摘要:Provided herein are multiplexible particle systems and related methods of making and using the multiplexible particle systems. A plurality of monodisperse polymer particle populations are provided, wherein each population has a unique electrical parameter for multiplexed detection by flow through a spatially confined electric field, and the distribution of the electrical parameter within each population is sufficiently narrow for reliable multiplex detection. The density difference between populations may be relatively uniform, such as within 30%, including within 30% of a suspending solution density for when the particles are flowed through a confined electric field and detected in a multiplex manner by a change in the electric parameter measured by a counting device. Relatively uniform density of particles is important for ensuring minimal settling while the plurality of particle populations flow together under a single flow regime. The multiplexible particle systems are used in applications including multiplex detection or quantification, electrically barcoding, sorting, and counting.

摘要:New fluorinated ethers of aromatic acids and diesters are disclosed. These compositions can be applied to, e.g., fibers, yarns, carpets, garments, films, molded parts, paper and cardboard, stone, and tile to impart soil, water and oil resistance. By incorporating the fluorinated ethers of aromatic acids, or diesters thereof, into polymer backbones, more lasting soil, water and oil resistance, as well as improved flame retardance, can be achieved.

摘要:This application is directed to novel fluorinated polymers and prepolymers derived from mono-substituted oxetane monomers having fluorinated alkoxymethylene side-chains and the method of making these compositions. The mono-substituted fluorinated oxetane monomers having fluorinated alkoxymethylene side-chains are prepared in high yield by the reaction of a fluorinated alkoxides with either 3-halomethyl-3-methyloxetane premonomers or aryl sulfonate derivative of 3-hydroxymethyl-3-methyloxetane premonomers. Preparation of a mono-substituted 3-bromomethyl-3-methyloxetane premonomer via a simple, high yield process amenable to commercial scaleup is also disclosed. The fluorinated oxetane monomers of this invention can be readily homo/co-polymerized in the presence of a Lewis acid and polyhydroxy compounds to obtain hydroxy-terminated polyether prepolymers having fluorinated alkoxymethylene side chains. Additionally, the fluorinated oxetane monomers can be copolymerized with non-fluorinated monomers such as tetrahydrofuran to give polyether prepolymers with improved hydrocarbon compatibility. These prepolymers are polydisperse and exhibit number average molecular weights from 5,000 to about 50,000. These prepolymers are amorphous oils with primary hydroxy end-groups and thus function efficiently as the soft block for the synthesis of a variety of thermoset/thermoplastic elastomers and plastics having the characteristics of very low surface energy, high hydrophobicity, low glasss transition temperature and low coefficient of friction. The polyurethanes derived from the prepolymers of this invention are elastomeric and, in addition to the above characteristics, exhibit high moisture resistance, high tear strength and excellent adhesion to a variety of substrates.
