ABSTRACT:
There is provided a process comprising polymerizing a compound selected from the group consisting of a conjugated diene, a vinyl-substituted aromatic compound, and mixtures thereof in a gas phase fluidized polymerization vessel under polymerization conditions in the presence of at least one anionic initiator, optionally in the presence of an inert particulate material. A novel resin particle produced by the process is also provided.
