Modified polymers and stable emulsions comprising the same

A modified polymer includes a diene-based polymeric chain and at least one end terminated with a blocked isocyanate group. The blocked isocyanate group may be the reaction product of an isocyanate and a blocking agent, and the blocking agent is selected, such that the modified polymer deblocks at temperatures of at least 100 C. An aqueous emulsion of the modified polymer may be provided that may be surfactant-free. The emulsion may be combined with one or more latexes to provide a treatment solution for a fabric or fiber that does not require the use of resorcinol and formaldehyde. Once treated and dried, the fabric or fiber may be used to impart tensile strength to rubber products, such as tires, air springs, flexible couplings, power transmission belts, conveyor belts, and fluid routing hoses.

Antifouling and chlorine-resistant ultrathin coatings on reverse osmosis membranes

Disclosed are methods of preparing antifouling and chlorine-resistant coatings on reverse osmosis membranes with initiated chemical vapor deposition. The coatings enhance the stability and lifetime of membranes without sacrificing performance characteristics, such as permeability or salt retention.

CARBON MATERIAL DISPERSION

There is provided a carbon material dispersion which has excellent dispersibility and in which the dispersibility is retained stably over a long period of time even when the carbon material dispersion contains a carbon material at a high concentration. The carbon material dispersion is a carbon material dispersion containing a carbon material, water, and a polymeric dispersant, wherein the polymeric dispersant is a polymer including 5 to 40% by mass of a constituent unit (1) derived from a monomer 1, such as 2-vinylpyridine, 50 to 80% by mass of a constituent unit (2) derived from a monomer 2 represented by formula (1) (wherein R.sub.1 represents a hydrogen atom or the like, A represents O or NH, X represents an ethylene group or a propylene group, Y represents O, NHCOO, or NHCONH, each of R.sub.2 represents a hydrogen atom or the like, n represents 20 to 100, and R.sub.3 represents a hydrogen atom or the like), and 0.5 to 40% by mass of a constituent unit (3) derived from a monomer 3 copolymerizable with above-described monomers.
