Triblock copolymer nanotubes bearing end-exposed poly(acrylic acid) or PAA core chains were prepared. The exposed PAA chains were reacted by amidization with a large excess of polystyrene spacer chains possessing amino end groups or amino-containing endblocks to graft the spacer chains. The amino groups at the other end of the spacer chains were then reacted with nanospheres bearing surface carboxyl
This invention discloses a functional monomer, its use in a polymer, a rubbery composition, a tire, and a process to make such a rubbery composition. The functional monomer has a structural formula selected from the group consisting of:
wherein the R1 groups can be the same or different and represent hydrogen atoms or alkyl groups containing from 1 to 8 carbon atoms, wherein R2 represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms, wherein R3 represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms, wherein R4 represents a hydrogen atom or an alkyl group containing from 1 to 8 carbon atoms, with the proviso that if R3 represents an alkyl group then R4 represents a hydrogen atom, and with the proviso that R4 represents an alkyl group then R3 represents a hydrogen atom, and wherein the R5 groups can be the same or different and represent alkyl groups containing from 1 to 8 carbon atoms.
