Claims26
A triazine ring-containing polymer characterized by comprising repeating unit structures represented by the following formula:
- wherein R and R′ independently from each other mean a hydrogen atom or an alkyl, alkoxy, aryl or aralkyl group, and Ar means at least one selected from the group consisting of groups represented by the following formulas (3) to (19):
- wherein
- R1 to R128 independently from each other mean a hydrogen or halogen atom, or a carboxyl, sulfone, branched or unbranched C1 to C10 alkyl or branched or unbranched C1 to C10 alkoxy group,
- W1 means a single bond, C═O or NR129 in which R129 means a hydrogen atom or a branched or unbranched C1 to C10 alkyl group,
- W2 and W3 independently from each other mean a single bond, CR130R131 in which R130 and R131 independently from each other mean a hydrogen atom or a branched or unbranched C1 to C10 alkyl group with a proviso that these alkyl groups may be fused together to form a ring, CO═O, S, SO, SO2, or NR129 in which R129 has the same meaning as defined above, and
- X1 and X2 independently from each other mean a single bond, a branched or unbranched C1 to C10 alkylene group, or the following formula (20):
- wherein R132 to R135 independently from each other mean a hydrogen or halogen atom, or a carboxyl, sulfone, branched or unbranched C1 to C10 alkyl or branched or unbranched C1 to C10 alkoxy group, and Y1 and Y2 independently from each other mean a single bond, or a branched or unbranched C1 to C10 alkylene group.
A process for producing a triazine ring-containing hyperbranched polymer, characterized by heating at from 60 to 150° C. a solution of a cyanuric halide or diaminoaryl compound and an organic solvent contained therein, and adding the diaminoaryl compound or cyanuric halide to the solution at the temperature to obtain the triazine ring-containing hyperbranched polymer in a single step.
A process for producing a triazine ring-containing hyperbranched polymer, characterized by comprising a first step of reacting a cyanuric halide and a diaminoaryl compound at from −50 to 50° C. in an organic solvent, and subsequent to the step, a second step of conducting a reaction at from 60 to 150° C.
A process for producing a triazine ring-containing hyperbranched polymer, characterized by polymerizing a cyanuric halide compound and a diaminoaryl compound in the presence of from 0.05 to 500 equivalents, based on the cyanuric halide compound, of an organic monoamine.
A composition characterized by comprising a triazine ring-containing hyperbranched polymer, which comprises repeating unit structures represented by the following formula (1′):
- wherein R and R′ independently from each other mean a hydrogen atom or an alkyl, alkoxy, aryl or aralkyl group, and Ar′ means a divalent organic group containing at least one of an aromatic ring and a heteroring, and a crosslinking agent.
A hyperbranched polymer by having a weight average molecular weight of from 500 to 500,000, a refractive index at 550 nm of at least 1.70, and being free of any sulfur atom in a molecule thereof.
