    摘要： The production method of the present invention includes: a supplying step of supplying reaction raw materials to at least one of a plurality of reaction vessels mutually communicated through a gas phase; a polymerizing step of carrying out a polymerization reaction; and a step of removing at least some of the water present in the reaction vessels. Each of the steps is carried out in parallel, and a reaction mixture is transferred sequentially between the reaction vessels. The total amount of water contained in the reaction raw materials in at least one of the reaction vessels to which the reaction raw materials are supplied is 3 moles or more per mole of the sulfur source, and the internal temperature of at least one of the reaction vessels to which the reaction raw materials are supplied is from 180° C. to 300° C.

Each of the steps is carried out in parallel, and a reaction mixture is transferred sequentially between the reaction vessels. The amount of water contained in the reaction mixture in at least one of the reaction vessels is from 0.1 moles to less than 3 moles per mole of a sulfur source, and the total amount of water contained in the reaction raw materials that are supplied is 3 moles or more per mole of the sulfur source.

    摘要： The production method of the present invention includes a step of supplying an organic polar solvent, a sulfur source, and a dihalo aromatic compound as reaction raw materials to at least one of a plurality of reaction vessels mutually communicated via a gas phase; a step of removing at least a portion of the water present in the reaction vessels; and a step of performing a polymerization reaction. These steps are carried out in parallel, and the reaction mixture is sequentially moved between reaction vessels. At that time, the internal temperatures of the reaction vessels are all not less than 150° C.

    摘要： In some cases, fabricating a high refractive index polymer composite may include combining a thiol monomer and an ene monomer to yield a composite mixture, heating the composite mixture to yield a homogenous composite mixture, and curing the homogeneous composite mixture to yield a polymer composite, wherein the ene monomer comprises zirconium oxo (meth)acrylate clusters. The refractive index of the high refractive index polymer composite may be at least 1.70. In certain cases, fabricating a high reactive index polymer composite includes combining a vinyl (ene) monomer, a thiol monomer, and zirconium oxo (meth)acrylate clusters to yield a composite mixture, heating the composite mixture to yield a homogenous composite mixture, and curing the homogeneous composite mixture to yield a polymer composite. The refractive index of the high refractive index polymer composite may be at least 1.75.
