摘要:
This invention is a composition comprising (a) an oligomer or polymer dispersible in an organic solvent, having a low dielectric constant, or being curable to form a material having a low dielectric constant, (b) at least one organic solvent and (c) less than 1000 parts by weight of a polymeric coating additive per million parts by weight of total composition (ppm). The polymeric additive is characterized in that it is miscible with component (a) and the solvent system but becomes incompatible with the mixture of component (a) and solvent during the coating process.

The present invention is directed to a hydrogenated block copolymer of a vinyl aromatic and butadiene which is useful in the preparation of optical media discs having very low birefringence.
摘要:
Organic compounds are hydrogenated in the presence of certain monocyclopentadienyl Group IV metal compounds. These titanium compounds are effective hydrogenation catalysts for polymers containing ethylenic unsaturation. They further provide for selective hydrogenation of ethylenic unsaturation sites in the presence of aromatic groups.
摘要:
The invention relates to functionalized interpolymers derived from base olefin interpolymers, which are prepared by polymerizing one or more monomers or mixtures of monomers, such as ethylene and one or more comonomers, to form an interpolymer products having unique physical properties. The functionalized olefin interpolymers contain two or more differing regions or segments (blocks), resulting in unique processing and physical properties.
摘要:
The present invention is an article of construction formed from an article adhesively-bonded to a layering material through (a) reactive coupling of a functionalized nitroxide or (b) the adhesion of components in a polymer matrix made from or containing a polymer, an organic peroxide, and a functionalized nitroxide. The initial article may be expanded. The initial article may be expanded. It may also be polar or nonpolar. Similarly, the layering material may be polar or nonpolar. Other embodiments of the present invention are described, including other articles and methods for preparing the articles.The useful articles of the present invention include shoe outsoles and midsoles, paints, overmolded articles, weather stripping, gaskets, profiles, durable goods, tires, construction panels, leisure and sports equipment foams, energy management foams, acoustic management foams, insulation foams, other foams, automotive parts (including bumper fascias, vertical panels, soft thermoplastic polyolefin skins, and interior trim), toys, supported films (including single-ply and co-extruded films), glass laminations, leather articles (synthetic and natural), personal health care and hygiene articles, other metal laminates, wood composites, and filled articles.
摘要:
The present invention is a method for oxyfunctionalizing, that is, introducing oxygen functionality to, a polyolefin such as polypropylene and poly(ethylene-alt-propylene). The polyolefin is contacted with an oxygen source such as a persulfate and catalytic amounts of a metal porphyrin complex under mild conditions to yield an oxyfunctionalized polymer that has a polydispersity that is very similar to that of the starting polymer.
摘要:
Sulfonated substantially random interpolymers made from monomer components comprise from 1 to 65 mole percent of (a) at least one vinyl or vinylidene aromatic monomer, or (b) at least one hindered aliphatic or cycloaliphatic vinylidene monomer, or (c) a combination of at least one vinyl or vinylidene aromatic monomer and at lest one hindered aliphatic or cycloaliphatic vinylidene monomer, and from 35 to 99 mole percent of at least one aliphatic &agr;-olefin having from 2 to 20 carbon atoms; and optionally, from 0 to 20 mole percent of a diene containing from 4 to 20 carbon atoms; wherein the sulfonated interpolymer contains at least one mer (or moiety) of a group represented by the formula —SO3M where M is hydrogen or a group 1, 7 or 12 metal in ionic form or combination thereof. Blends of these polymers with polyamides and polyolefins are made.
