Patent ID: 7115683

Claim:
An organic-inorganic nanocomposite composition, comprising: a) a layered silicate salt, wherein i) a cationic initiator and ii) a cationic chain transfer agent are ion-exchanged in a layered silicate compound; and b) a polymer medium; wherein the a) ii) cationic chain transfer agent is able to lead to living radical polymerization, represented by Chemical Formula 3: (In the Chemical Formula 3, Z is a hydrogen, a chlorine, an alkyl, an alkylthio, an alkoxycarbonyl, an aryoxycarbonyl (—COOR″), an carboxy (—COOH), an acyloxy (—O 2 CR″), a cabamoyl (—CONR″), a cyano (—CN), a dialkyl-phosphonato, a diaryl-phosphonato (—P(═O)OR″ 2 ), a dialkyl-phosphinato, a diaryl-phosphinato (—P(═O)R″ 2 ) which contains or does not contain substitutents, R″ is C 1-18 alkyl, C 18 alkenyl, aryl, heterocyclyl, aralkyl, or alkylaryl which contains or does not contain substitutents selected from the group of epoxy, alkoxycarbonyl, aryloxycarbonyl, isocyanto, cyano, silyl, haloyl, and dialkylamino, R 1 is C 1-18 alkyl, C 2–18 alkenyl, aryl, heterocyclyl, aralkyl, or alkylaryl which contains or does not contain substitutents selected from the group of hydrogen, ester, keto, amide, ether, thio, hydroxy, cyano, silyl, haloyl, and dialkylamino, and R 2 and R 3 are independently C 1-18 alkyl, C 2-18 alkenyl, aryl, heterocyclyl, aralkyl, or alkylaryl which contains or does not contain substitutents are selected from the group of hydrogen, ester, keto, amide, ether, thio, hydroxy, cyano, silyl, haloyl, and dialkylamino, and at least one of R 2 and R 3 contains ammonium salt represented by Chemical Formula 4 or Chemical Formula 5 having a cationic substitutent at its end): (In the Chemical Formula 4: R 4 , R 5 , and R 6 are independently an alkyl which contains branches, normal saturated or unsaturated alkyl which contain aryl substitutent, alkoxyalkyl, cyanoalkyl, or hydroxyalkyl, X is a halide or sulfate having a functional group capable of forming a salt or an anion), (In the Chemical Formula 5, The hetero ring is a ring compound having a 5,6-square shape, and can contain independently an alkyl or alkene, nitrogen can be 1 to 3, Q is a halide or a sulfate having a functional group capable of forming a salt or an anion).
