摘要:
The invention can provide a high-refractive-index resin composition containing particles, more particularly, a resin composition having a high refractive index and usable in optical applications including coatings and lenses. The high-refractive-index resin composition of the invention is a high-refractive-index resin composition obtained by polymerizing a polymerizable composition containing particles coated with a surface-treating agent and having an average particle diameter of 10 nm or smaller and a polymerizable monomer, wherein the content of the particles excluding the surface-treating agent, X (% by mass), and the refractive index of the high-refractive-index resin composition, Y (n23d), have a relationship between these which is represented by the general formula 1: Y≧0.0035X+1.52 (wherein 20≦X≦60 and Y≦2.0).
摘要:
Disclosed is a process for producing a powdered water-soluble polymer comprising hydrolyzing a copolymer comprising an N-vinylamide unit and a vinyl acetate unit while dispersed in water under a basic condition and then washing the resulting powdered water-soluble polymer with at least one washing liquid selected from an alcohol, water at 20° C. or lower, and salt water.
摘要:
Dendritic macroinitiator compositions are provided comprising a compound of the general formula, Fx-[G-n]-I, where F is the chain end functional group of the dendrimer, x is the number of chain end functional groups, G is the dendrimer, n is the generation number of the dendrimer, and I is the initiating group. Hybrid dendritic-linear copolymers made from these macroinitators can act as highly efficient dispersing agents for a range of nanoparticles in matrix materials.
