摘要： The present disclosure provides a gel electrolyte precursor and use thereof. The gel electrolyte precursor comprises a gel matrix monomer, a flexible additive, a polymerization initiator, and a lithium salt. The gel matrix monomer comprises an acrylonitrile-based monomer. The use of same in a semisolid battery achieves good electrical performance, and also reduces the amount of an electrolyte used. An acrylonitrile-based polymer obtained by the in-situ polymerization and gelation of an acrylonitrile-based monomer has good flame retardant performance and high voltage resistance, improving the safety performance of a battery.

摘要： Methods for processing LDPE recyclates including, but not limited to, polyethylene and polypropylene and compositions therefrom are provided. LDPE recyclate can be visbroken to improve processing characteristics and/or devolatilized to remove waste byproducts to produce processed LDPE recyclates. Processed LDPE recyclates are compounded with pre-consumer polyolefins to produce blend compositions having acceptable or even improved processing characteristics. Such pre-consumer polyolefins can also be visbroken to further tailor processing characteristics of such polymer blends. A combination of extruders and/or extruder zones can be used at the same or different locations for visbreaking and/or compounding of both LDPE recyclate and/or pre-consumer polyolefins.

摘要： The present invention discloses methods for removing volatile components from an ethylene polymer effluent stream from a polymerization reactor, and related polyethylene recovery and volatile removal systems. In these methods and systems, the polymer solids temperature is increased significantly prior to introduction of the polymer solids into a purge column for the final stripping of volatile components from the polymer solids.

摘要： The present invention provides a process for making a silica masterbatch that contains hydrophobated silica, solution-made rubber and emulsion-made rubber. Hydrophobated silica is mixed into a latex emulsion. Solution-rubber crumb in an aqueous suspension is mixed into the latex emulsion, which is coagulated, and a crumb is recovered, further homogenized, dried and baled to yield the silica masterbatch. A well-dispersed mixture of hydrophobated silica and emulsion-made rubber is added into a steam distillation step of a solution-rubber process from which a silica masterbatch is recovered. The emulsion-made rubber can be omitted to make a silica masterbatch of solution rubber and silica without emulsion rubber. The silica masterbatch has physical properties similar to those found in a comparable dry-mixed composition, but the silica masterbatch can be incorporated more easily and less expensively into tires and other rubber products than the dry-mixed composition.
