摘要： Blends of substantially linear ethylene polymers, for example, polyethylenes prepared by constrained geometry catalysis, which are grafted with one or more olefinically unsaturated organic compounds, for example, maleic anhydride, and another thermoplastic polymer, for example, a polyester or a polyamide demonstrate desirable impact properties at both ambient and low temperatures (for example, -30 °C).

摘要： Methods for devolatilizing polymer solutions have been invented which include, in certain aspects, dissolving a viscous polymer in a solvent forming a polymer-solvent solution, introducing the polymer-solvent solution into a thermal dryer, heating or cooling the polymer-solvent solution in the thermal dryer forming product polymer with solvent removed and separated solvent (which may include other residuals), the separated solvent with other residuals if present vaporizing in the thermal dryer forming a vapor, removing the vapor from the thermal dryer, and discharging product polymer from the thermal dryer.

摘要： L'invention concerne un procédé d'amélioration de la stabilité thermique oxydative de polymères d'éthylène qui consiste à éliminer le ou les monomères résiduels n'ayant pas réagi, le solvant et les espèces thermiquement instables du polymère en utilisant un agent séparateur et une dévolatilisation ultérieure. Le polymère obtenu se caractérise en ce qu'il possède un pourcentage exothermique oxydatif n'excédant pas 50 % du polymère original, valeur mesurée par calorimétrie de balayage différentiel, ainsi que des propriétés améliorées de goût et d'odeur.

摘要： A homogeneous, random interpolymer of ethylene and an alpha-olefinically unsaturated carboxylic acid or ester having melt indices from 0.1 to 300 grams/10 minutes, as determined by ASTM D-1238 (190 °C/2160 grams), is improved during its manufacture when made in a substantially constant environment in a stirred autoclave under substantially steady-state conditions of temperature, pressure, and flow rates, said temperature and pressure being sufficient to produce a single phase reaction, using a free-radical initiator, said improvement being obtained by the use of a minor amount of a telogenic modifier in the reaction mixture, the process being further characterized by the use of either, or both, of (a) a temperature which is lower than that which would be required without the presence of the telogen, or (b) a pressure which is higher than that which would be required without the presence of the modifier.

摘要： A process of reacting a poly(sulfonyl azide) with a polymer comprising steps (a) forming a first admixture, hereinafter referred to as a concentrate, of a first amount of a first polymer or in a liquid which does not require removal from the polymer, hereinafter diluent, and a poly(sulfonyl azide); (b) then forming a second admixture of the first admixture with a second amount of at least one second polymer, hereinafter second polymer composition; and (c) heating the second admixture to the decomposition temperature of the coupling agent for a time sufficient to result in coupling of polymer chains. The diluent is miscible. The first polymer is selected from ethylene alpha olefin copolymers; ethylene acrylic acid; ethylene vinyl acetate, ethylene/styrene interpolymers preferably steps (a) and (b) take place in the same vessel, which is preferably in the post-reactor area of a polymer processing plant.

摘要： A method of improving the oxidative thermal stability of ethylene polymers is disclosed. The method comprises removing residual unreacted monomer(s), solvent and thermally unstable species from the polymer using a stripping agent and subsequent devolatilization. The resulting polymer is characterized by having an oxidative exotherm of not more than 50 percent of the original polymer, as measured by differential scanning calorimetry, as well as improved taste and odor properties.

摘要： The subject invention is directed to a rheology-modified ethylene polymer having less than 0.5 weight percent gel, a composition distribution breadth index (CDBI) greater than 50 percent, and a molecular weight distribution (Mw/Mn) of less than 4.0, which is characterized as having improved rheological performance and/or melt strength attributes relative to the unmodified polymer. The subject invention is further directed to polymer blends which comprise the rheology-modified polymers, and to a process for preparing the rheology-modified polymers.
