Disclosed are a latex polymer of multi-stage polymerization comprising a first stage polymer and a second stage polymer wherein the first stage polymer comprises a first portion of an acrylic monomer and a first portion of a phosphorus acid monomer, and the second stage polymer comprises a second portion of an acrylic monomer and a second portion of a phosphorus acid monomer, a process of making the same, and coating composition made thereof.


Patent
Rohm And Haas Company | Date: 2017-01-18

Provided is an aqueous adhesive composition comprising a polymer that comprises (a) polymerized units of one or more alkyl (meth)acrylate monomer, (b) polymerized units of acrylic acid or methacrylic acid or a mixture thereof, (c) polymerized units of one or more dialkyl diester of itaconic acid, and (d)polymerized units of one or more other monomer.


Patent
Rohm And Haas Company | Date: 2017-02-07

A composite polymer composition comprising the emulsion polymerization product of: (i) an aqueous dispersion comprising the melt kneading product of one or more polyolefins, from 2 to 25 wt % of one or more dispersion stabilizing agents, water and optionally a neutralizing agent, and (ii) one or more (meth)acrylic monomers; wherein the one or more polyolefins have a Tg equal to or less than 50 C. and comprise from 0.5 to 100 wt % functionalized polyolefin; and wherein the melt kneading product (i) comprises polymer particles having a volume average particle size between 150 nm and 2000 nm dispersed in the water; and wherein the one or more (meth)acrylic monomers polymerize onto the polymer particles form composite polymer particles using an emulsion polymerization process is provided.


Patent
The Regents Of The University Of California, Dow Chemical Company and Rohm And Haas Company | Date: 2017-02-02

The present invention is a multilayered composite comprising porous metal oxide particles that are covalently bonded by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer. This first polymer is in turn covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. The multilayered composites can be prepared by contacting porous inorganic-oxide particles with a sufficient amount of OH-reactive crosslinking agent to form metal oxide particles imbibed with the crosslinking agent, and then contacting the inorganic-oxide particles with a solution of polyhydroxyl-functionalized polymer under reactive conditions.


Patent
Rohm And Haas Company | Date: 2017-02-07

An aqueous adhesive composition including a certain emulsion polymer and an epoxysilane wherein the adhesive composition is substantially free from crosslinking agent is provided. A method for providing a substrate bearing a paper label, the adhered label having ice water resistance, and a method for removing the paper label from the substrate are also provided.


Patent
Dow Chemical Company and Rohm And Haas Company | Date: 2017-01-18

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.
