Abstract:
The present invention relates to a method of manufacturing homogenous styrene-based polymer beads using the pre-polymerization of styrene-based monomers and, more specifically, to a novel method of manufacturing homogenous styrene-based polymer beads which obtains styrene-based polymers of a oligomer state through a pre-polymerization (bulk polymerization), adds crosslinking agents and polymerization initiators, forms droplets, produces polymers by performing partial polymerization on the droplets and transfers the produced polymers to a polymerization unit for main polymerization, wherein the produced polymers maintain droplet shapes and homogenous styrene-based polymer beads are stably manufactured since the produced polymers stably transferred. When the styrene-based polymer beads are manufactured according to the present invention, the uniformity of the polymer beads are improved as compared to a method using the existing monomer solution, and productivity and economic feasibility are increased by reducing time required in polymerization and the length of a column.

In-situ preparation of substrates with dispersed gold nanoparticles is provided to achieve high density and stabilization of protein by three-dimensionally dispersing the gold nanoparticles on the substrates. A polycation thin film is formed on substrates by dipping the substrates into a polycation polymer solution. A polymer thin film of a polycation polymer and a polyanion polymer is formed on the substrates by dipping the substrates into a polyanion polymer solution. The substrates are dipped into a reducible-gold compound solution. The gold nanoparticles are dispersed on the polymer thin film by reducing the reducible-gold compound so that substrates with dispersed gold nanoparticles are prepared.
