摘要： Polymer foam bodies are made from phosphorus-containing thermoplastic random copolymers of a dialkyl (meth)acryloyloxyalkyl phosph(on)ate. Foam bodies made from these copolymers exhibit increased limiting oxygen indices and surprisingly have good properties. In certain embodiments, the phosphorus-containing thermoplastic copolymer is blended with one or more other polymers and formed into nanofoams.

One component of the blend will be characterized as having either a density in the range of from 0.855 to 0.88 g/cm3 or a residual crystallinity at 80° C. of greater than 9 percent but not both. The at least one other component will meet at least whichever characteristic the first component does not meet.

摘要： A polymer composition comprises a low-molecular-weight (LMW) ethylene polymer component and a high-molecular-weight (HMW) ethylene polymer component coupled with a polysulfonyl azide. Preferably, the LMW polyethylene component and the HMW polyethylene component co-crystallize in the composition such that it exhibits a single or substantially single peak in a lamella thickness distribution (LTD) curve. The ethylene polymer for the LMW and the HMW polyethylene components can be either homopolymer or ethylene copolymer. Preferably, both components are an ethylene copolymer of the same, or different, composition (that is, with the same or different comonomers). A method of making a pipe that includes selecting a polymer composition having a substantially single peak in the LTD curve is described. Compositions comprising a chromium-catalyzed ethylene polymer, coupled with a polysulfonyl azide are also described herein.

摘要： The present invention is a rheology-modifiable polymeric composition or a free-radical crosslinkable polymeric composition, wherein the resulting rheologymodifying bond or crosslinking bond is a thermally-reversible bond. The resulting polymer is prepared from at least one polymer which upon forming free radicals preferentially degrades or carbon-carbon crosslinks. The present invention permits suppression of the preferential reaction while permitting the polymer to be coupled or crosslinked through a thermally-reversible bond. Suppressing the undesirable degradation or carbon-carbon crosslinking reaction and permitting the desirable reaction yield a rheology-modified polymer or a free-radical thermally-reversibly crosslinked polymer.
