摘要:The present disclosure relates to a process to produce a reinforced elastomeric material and to the reinforced elastomeric material. The process comprises the steps of providing components comprising a grafted elastomer, one or more dianhydrides, and one or more diamines; wherein the grafted elastomer is provided at a content of at least 60 wt.% based on the total weight of the components; performing in situ synthesis of a polyimide phase in the grafted elastomer by reactive extrusion of the components in a twin-screw extruder comprising main hopper wherein the screw profile comprises two or more reverse conveying elements forming two or more hot zones to form an elastomer-polyimide blend; and recovering said elastomer-polyimide blend being a reinforced elastomeric material.

标题:Synthesis of cyclic trithiocarbonates from epoxides
发明人：PARKER DANE KENTON
权利人:GOODYEAR TIRE & RUBBER
摘要:This invention provides a low cost technique for synthesizing cyclic trithiocarbonates by a simple one step process from epoxides that can be conducted under atmospheric pressure. This synthesis can be depicted as follows: n nwherein R represents a moiety selected from the group consisting of alkyl groups and aryl groups, wherein R′ represents a moiety selected from the group consisting of alkyl groups, aryl groups, and hydrogen atoms, and wherein R″ represents a moiety selected from the group consisting of alkyl groups, aryl groups, and hydrogen atoms, wherein the R moiety and the R′ moiety can be bonded together to form a cyclic structure, with the proviso that R″ represents a hydrogen atom if R′ represents an alkyl group or an aryl group. In this process carbon disulfide and a thiocyanate salt, such as potassium thiocyanate, are reacted with the epoxide in an ionic liquid, such as 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim] PF 6 ) in the presence of water to produce the cyclic trithiocarbonate.
