Porous glass nanoparticles according to an embodiment have a specific surface area of 250 m2/g to 800 m2/g, and a pore volume of 0.1 cm3/g to 1 cm3/g. Since the porous glass nanoparticles have a high specific surface area and pore volume, the porous glass nanoparticles may have improved agilities to remineralize the demineralized dentin and occlude dentinal tubules. In addition, by including the porous glass nanoparticles, a dentin adhesive composition with improved adhesive strength to the dentin surface may be provided.

Porous glass nanoparticles and dentin adhesive composition comprising same

Provided are a novel transition metal compound, a transition metal catalyst composition for preparing an ethylene homopolymer or a copolymer of ethylene and &#x3b1;-olefin, containing the same, a method for preparing an ethylene homopolymer or a copolymer of ethylene and &#x3b1;-olefin using the same, and an ethylene homopolymer or a copolymer of ethylene and &#x3b1;-olefin prepared using the same.

Transition metal compound, transition metal catalyst composition for polymerizing olefin, containing same, and method for preparing ethylene homopolymer or copolymer of ethylene and alpha-olefin by using same

Provided are a plasticizer for a resin composition including any one or more selected from a polyvinyl chloride resin, a polyurethane resin, an epoxy resin, a polycarbonate resin or a biodegradable resin, which has excellent mechanical properties such as tensile strength, elongation and hardness, and shape processability, and particularly has excellent flexibility at low temperatures, does not cause bleeding because compatibility with the resins is good, and has excellent transparency, heat resistance, cold resistance and durability, and a resin composition including the same.

Plasticizers for resin compositions and resin compositions including the same

The present invention provides an ester plasticizer for polyvinyl chloride (PVC) resin, epoxy resin or urethane resin and a method of preparing the same. More particularly, the present invention provides an ester plasticizer using triacetin and coconut oil-based biodiesel as raw materials, which can prepare a resin composition having excellent plasticizing efficiency and improved physical properties such as tensile strength and the like. When a polyvinyl chloride resin or the like is manufactured using the ester plasticizer, there are advantages in that an environment-friendly product having an excellent plasticizing efficiency and in that the physical properties such as hardness, tensile strength, etc. of the product are improved.
