Abstract:
The present invention generally relates to vulcanization compositions used to vulcanize elastomeric articles, where the vulcanization compositions have reduced allergenic potential as compared to elastomeric articles formed using vulcanization compositions having non-fugitive accelerators. The present invention also relates to elastomeric articles formed using the vulcanization compositions. The invention further relates to methods for making a reduced-allergenicity vulcanization composition, and to methods for using the vulcanization compositions to vulcanize elastomeric articles.
Abstract:
A tire comprises a rubber composition based on at least one diene elastomer, a reinforcing filler predominantly comprising silica, a crosslinking system, and a hydroxyalkylpiperazine of formula (I): in which R1 represents a linear or branched alkyl group comprising from 1 to 18 carbon atoms, R2 represents a linear or branched alkylene group comprising from 1 to 18 carbon atoms, it being understood that R1 and R2 can bear one or more additional hydroxyl groups. The rubber composition is essentially devoid of guanidine derivative.
Abstract:
A method includes heating a sulfonated polyester resin in an organic-free solvent adding an aqueous solution of silver (I) ion to the heated resin to form a mixture and heating the mixture to effect the reduction of silver (I) ion to silver (0) in the absence of an external reducing agent. A composite includes a sulfonated polyester matrix and a plurality of silver nanoparticles dispersed within the matrix; the composite lacks trace residual byproducts from external reducing agents.
Abstract:
A rubber compound for tyres comprising a cross-linkable unsaturated chain polymer base comprising, in turn, at least a rubber of synthetic origin, a silica-free filler at least partially comprising carbon black, a vulcanization system and a mercapto carboxylic acid.
Abstract:
A method of making a fluoroelastomer composition includes curing a fluoroelastomer precursor composition under ambient pressure conditions resulting in a fluoroelastomer composition that is substantially free of surface bubbles. The fluoroelastomer precursor composition includes peroxide-curable fluoropolymer, an effective amount of peroxide consisting essentially of bis(2,4-dichlorobenzoyl) peroxide for curing the peroxide-curable fluoropolymer. The fluoroelastomer precursor composition is essentially free of non-fluorinated carbon particles. A method of making composite articles based on the method is also disclosed.
