Silica containing rubber composition

This invention discloses a method for preparing rubber compositions that exhibit unique combinations of properties that are desirable for tire tread applications for enhanced snow/ice and wet traction, low rolling resistance and increased treadwear performance in comparison with conventional silica compounds. Specifically, a high reactively silane coupling agent, such as a mercaptosilane, is used in combination with a silane coupling typically used for silica tread compounds such as bis(triethoxylsilylpropyl)disulfide to treat silica pellets in a hydrocarbon solvent at elevated temperatures. The treated silica is then blended with solution elastomer cement in a hydrocarbon solvent. The deposited reactive silanes partially react with the elastomer molecules forming a layer of polymer grafted on the silica surfaced. This structure significantly improves the silica retention during the steam stripping operation. Almost 100% (99+%) silica retention has been achieved by this invention. After solvent removal from steam stripping, the treated silica/elastomer mixer is dewatered and dried using conventional equipment such as shaker screens, expellers and expanders to form a well-dispersed silica masterbatch. This technique results in silica compounds with excellent silica dispersion and increased filler-polymer interaction, hence enhanced compound performance such as better physical properties, more desirable dynamic properties (low hysteresis at high temperatures and high hysteresis at low temperatures) and increased abrasion resistance.

High flow drapable polymer compositions

A thermoplastic pelletizable polymer composition comprising an oligomer or degraded polyolefin and an olefinic elastomer. Optionally, the composition can also include a polyolefin thermoplastic polymer. The composition, when converted to a film or fabric meets the criteria of drapability, low hardness on the Shore A scale, high melt flow and reprocessability.
