摘要： A continuous extrusion process for the functionalization of polymers through reactive extrusion. The process uses a continuous extrusion reactor comprising at least two sequential, very closely-coupled, independently driven screw extruders having a total effective length to diameter ratio greater than 60 to 1 and as high as 112 to 1 and providing greatly extended reaction times for efficiently producing a grafted polymer having a high level of functionalization. Drying of the polymer feed is performed in the continuous extrusion reactor. Multiple injections of reactants may be provided. Shear modification of the molecular weight 'of the grafted polymer is performed in the continuous extrusion reactor after the functionalization reactions. A continuous extrusion reactor and a grafted polymer having a high level of functionalization are also disclosed.

摘要： The invention relates to peroxide cured thermoplastic vulcanizates comprising a thermoplastic and an isomonoolefin-multiolefin elastomer, such as butyl rubber. More particularly, the invention relates to peroxide cured thermoplastic vulcanizates wherein the elastomer comprises at least 3.5 mol% of multiolefin in order to facilitate peroxide curing. The thermoplastic vulcanizates according to the present invention are useful in the preparation of shaped articles for high purity applications, such as condenser caps, medical components and fuel cell components.

摘要： The invention relates to a latex composition wherein the latex composition comprises a butyl ionomer or partially halogenated butyl rubber ionomer. The latex composition is formed by dissolving the butyl ionomer in a suitable solvent, emulsifying the polymer in the solvent, adding water and optionally a minor amount of a suitable surfactant system to the emulsion and concentrating the emulsion to remove the water. The advantages of butyl ionomer latex include lower emulsifier levels, increased latex stability, improved interaction and adhesion to polar substrates and surfaces. Through the judicious choice of emulsifiers and/or washing to remove excess emulsifier a film with enhanced non-extractable polymeric antimicrobial function can be created. These properties of ionomer latex are useful in coatings, dipped goods and sponge applications.

摘要： The present invention relates to processes for recycling articles made from butyl ionomers and processes for producing recycled butyl ionomers. The invention further relates to composites comprising recycled butyl ionomers and fillers and articles made from recycled butyl ionomers. The invention also relates to uncured filled articles made from butyl ionomers having certain physical properties. Exemplary fillers include silica, carbon black, talc and clay, particularly onium substituted high aspect ratio nanoclays.
