摘要： A composition for colloidal crystals includes core-shell particles (A) each having a core and a shell, and a monomer (B1) having a particular structure. The core-shell particles (A) constitute 25% to 65% by weight of the composition, and the monomer (B1) constitutes 35% to 75% by weight of the composition. The core has an average particle size in the range of 50 to 900 nm. The shell is formed of a linear polymer composed of at least one of styrene and a monomer (B2) having a particular structure. One end of the linear polymer is covalently bonded to the core. The refractive index of the core (n(core)) satisfies the following formulae (2) and (3): wherein R 1 denotes a hydrogen atom or a methyl group, and y is 0 or 1, n shell - n core ‰¥ 0.07 wherein n(shell) denotes the refractive index of the shell, and n B - n core ‰¥ 0.07 wherein n(B) denotes the refractive index of the monomer (B1) after curing.

摘要： A vinylated alkoxyamine represented by general formula (1) is produced by a process comprising the step of heating divinylbenzene together with a nitroxide compound and an organic peroxide to the heat decomposition temperature of the organic peroxide. In said formula, R1 represents aryl or R2O; R2 represents C¿1-12?, linear or branched (cyclo)alkyl; and R?3 and R4¿ each represents C¿4-6? tertiary alkyl or R?3¿ is bonded to R4 to form a C¿8-16? cyclic structure which is unsubsituted or substituted by any of aklyl, oxo, hydroxy, acyloxy, and alkoxy. A polymeric free-radical polymerization initiator having a pendant alkoxyamine group can be used to produce a graft polymer.
