    摘要: A GI type optical fiber of the present invention is a GI type optical fiber having a core component and a cladding component disposed around the outer periphery of the core component, the core component includes a polymer containing at least 55 wt % chlorostyrene monomer and a dopant, and the cladding component includes a polymer of a monomer containing at least 35 wt % methyl methacrylate. It is an object of the present invention to provide a GI type optical fiber in which chlorostyrene is used as the predominant component of the monomer that constitutes the core component, and therefore has excellent transparency and good flexibility, and allows high-speed communication.

    摘要: A process has been invented for removing contaminants (including solvent) from a flowing polymer, the process, in one aspect, including dissolving a sparingly soluble stripping agent into a flowing polymer, the sparingly soluble stripping agent stripping contaminants from the flowing polymer creating a mixture of contaminants and sparingly soluble stripping agent, which flows out from the flowing polymer, and separating the mixture from the polymer. In one aspect, recyclable sparingly soluble stripping agent is recovered and re-used.

    摘要: There is provided a method for the suspension polymerization of one or more styrenic monomers. This method involves increasing the amount of substantially water insoluble free radical initiator in the suspension after the conversion of the monomer has reached at least 50%. The temperature of the suspension is at least 110.degree. C. throughout the entire polymerization.
