| 20100152371 | METHOD FOR MAKING CHLORINATED POLYOLEFIN SOLUTIONS AND COATINGS - In method of making an organic solution of a chlorinated polyolefin that produces a storage-stable solution, a chlorinated polyolefin resin is dissolved in a hydrocarbon solvent that is predominantly aliphatic hydrocarbon, aromatic hydrocarbons other than toluene and xylene, or mixtures of these at a temperature of from 118 to 125° C., particularly at 120 to 122° C., held at the temperature for an adequate time for complete dissolution, particularly for at least about ninety minutes, then cooled and a cosolvent is added at a temperature below the boiling point of the cosolvent but at a temperature at which the chlorinated polyolefin solution is still clear or has little haziness, particularly at about 50 to 75° C. The solution may then be cooled, if needed, to a storage or use temperature. The solution has from about 60 to about 90 percent by weight of the mixture of the hydrocarbon solvent and cosolvent and from about 10 to about 40 percent by weight of chlorinated polyolefin resin. The solution has 0.1 to 10 wt % of the cosolvent.

| 20110218298 | METHOD FOR THE PREPARATION OF POLY (DISULFIDE) POLYMERS AND GELS - High molecular weight disulfide polymers are synthesized in aqueous media by exposing dithiol compounds to a mild oxidizing environment in the presence of a tertiary amine catalyst. The unique oxidizing system polymerizes monomers through the formation of sulfur-sulfur bonds between dithiol compounds. The same oxidizing system may be used to make disulfide-crosslinked gels from compounds containing multiple thiol groups. The oxidizing system is comprised of oxygen at atmospheric concentration and dilute hydrogen peroxide. A filler such as carbon black may be incorporated into the polymer or cross-linked gel during polymerization. A polydisulfide polymer is provided having a weight average molecular weight of greater than about 100,000 g/mol and a polydispersity index of about 2 or less. A tetrathiol composition results from a reaction of a diacrylate with a trithiol. The tetrathiol composition may be subjected to an oxidizing environment with a tertiary amine catalyst to provide a polytetrathiol polymer network. | 09-08-2011 |
| 20120083572 | STYRENIC (METH)ACRYLIC OLIGOMERS - Styrenic (meth)acrylic oligomers that are prepared at lower temperature than conventional solid grade oligomers, or are hydrogenated, contain fewer terminal vinylic unsaturations, when compared to such conventional styrenic (meth)acrylic oligomers prepared by the customary high temperature processes. Styrenic (meth)acrylic oligomers that contain fewer terminal vinylic unsaturations demonstrate improved thermal stability and may provide improved resistance to UV weathering compared to the conventional and non-hydrogenated styrenic (meth)acrylic oligomers. | 04-05-2012 |
