Abstract
Official abstract text for this publication.
A functionalized polymer includes the reaction product of a reactive polymer and a compound that includes an aryl group having at least one directly bonded OG p substituent, where G p is a protecting group, and a substituent (Q) which is free of active hydrogen atoms and which is, or connects to the aryl group through, a moiety that includes a carbon-to-nitrogen multiple bond. The polymer can be provided from a solution that includes one or more types of ethylenically unsaturated monomers which include at least one type of polyene, particularly one or more conjugated dienes in certain embodiments. An active terminus of the resulting reactive polymer can react with the Q substituent of the compound so as to provide a polymer having as a terminal functionality the radical of a compound that includes an aryl group having at least one directly bonded OG p substituent.
First claim
Opening claim text (preview).
That which is claimed is: 1. A process of providing a functionalized polymer comprising allowing a terminally active polymer to react with a compound comprising an aryl group that comprises at least one directly bonded OG p substituent, where G p is a protecting group selected from trihydrocarbylsilyl, benzyl, t-butyl, alkoxyalkyl, tetrahydropyranyl, allyl, sulfonamide, and pivalates, and a second type of substituent, said second type of substituent being free of active hydrogen…
