Patent
Dow Chemical Company, Rohm, Haas Electronic Materials LLC and Rohm And Haas Company | Date: 2017-03-22

Arylclobutene-containing multi-functional monomers are useful in the preparation of arylcyclobutene-based polymer coatings. Compositions comprising one or more arylclobutene-containing multi-functional monomers and one or more oligomers comprising as polymerized units one or more arylcyclobutene monomer provide arylcyclobutene-based polymer coatings having reduced stress. Such compositions are useful in the manufacture of electronic devices.


Patent
Dow Chemical Company and Rohm And Haas Company | Date: 2017-01-25

The present invention provides substantially isocyanate-free multicomponent compositions useful in making rapid dry primer compositions and coatings, the compositions comprising one or more carboxylic acid compounds that contain one of a benzothiazole, benzoxazole, or benzimidazole group, preferably, that contain a benzothiazole group, one or more hydrophobic sulfonic acid catalyst, one or more pigment, extender or filler, one or more a) polycarbamates from alkyd polyol or acrylic polyol and one or more b) a polyaldehydes or the acetal or hemiacetal thereof as a second component. The multicomponent compositions cure quickly at a temperature of from 0C to less than 80C to form a crosslinked polyurethane coating having improved humidity and corrosion resistance.

The present invention provides aqueous composition comprising a multi-stage acrylic emulsion polymer having a first stage polymer of from 0.5 to 4 wt.%, based on the total weight of monomers used to make the first stage polymer, of a copolymerized carboxylic acid or salt group containing monomer, and having 10 to 30 wt.%, on total solids of the multi-stage acrylic emulsion polymer, of a second stage polymer of from 3 to 15 wt.% of a copolymerized hydroxyl group containing monomer, the first stage polymer having a glass transition temperature (Tg) by dynamic mechanical analysis (DMA) of less than -10C and the second stage polymer having a Tg (DMA) of greater than 80C; and (ii) from 25 to 75 wt.%, based on the total solids weight of the multi-stage acrylic polymer, of a polyurethane.


The present invention relates to a composition comprising an aqueous solution of a hydrophobically modified alkylene oxide urethane polymer (HEUR), a bismuth salt, and at least one sediment abating compound selected from the group consisting of citric acid or a salt thereof, gluconic acid or a salt thereof, and a salt of ethylenediamine tetraacetic acid. The composition with the specific sediment abating compounds shows excellent abatement in sediment and color formation in heat age testing of the solution.


The present invention relates to a composition comprising an aqueous dispersion of an associative thickener having a hydrophobic portion with a calculated log P in the range of from 2.7 to 5.0; and composite particles comprising phosphorus acid functionalized polymer particles adsorbed to the surfaces of TiO_(2) particles; wherein the phosphorus acid functionalized polymer particles have a core-shell morphology wherein the core protuberates from the shell. The composition of the present invention provides formulators with flexibility in their use of low and mid shear rate thickeners to balance paint performance properties.

Compositions of nanoparticles are stabilized by capping agents which are composed of methacrylic acid and n-butylmethacrylate random copolymers having hydrophobic and hydrophilic moieties and low molecular weight. The nanoparticle compositions have low viscosity, high nanoparticle loading and may be selectively applied to substrates by methods such as inkjet, aerosol and electrospinning.

The present invention is a composition comprising a) an aqueous dispersion of TiO_(2) particles encapsulated with an encapsulating acrylic or styrene-acrylic polymer comprising from structural units of diacetone acrylamide; and b) adipic acid dihydrazide. The composition is useful in coatings applications and shows a surprising improvement in gloss over compositions that do not include diacetone acrylamide functionalized encapsulating polymer and adipic acid dihydrazide.


Patent

Provided are hair care compositions comprising: (a) a polyolefin oil blend comprising (i) at least one metallocene catalyzed polyolefin with a density above 0.90 g/cm3, (ii) at least one metallocene catalyzed polyolefin with a density equal to or below 0.90 g/cm3, and (iii) a cosmetically acceptable hydrocarbon oil; (b) a thickener; and (c) a humectant; wherein the high and low density polyolefins have an average melt index greater than 7, wherein the polyolefin blend is present in a range of from 0.1 to 1.4 weight % by weight of the composition, and wherein the composition is substantially free of ethylene-acrylic acid copolymer.


Patent
Dow Chemical Company and Rohm And Haas Company | Date: 2017-03-01

A method for inhibiting silica scale formation in an aqueous system by adding a hydrophobically-modified alkylene oxide urethane copolymer anti-scalant to the water used in the aqueous system.


Patent
