Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 264 words
A silicone emulsion composition obtained by emulsion-polymerizing: (1) 0.1-60 weight percent of a reaction product of: (A) 50-99.9 weight percent of a polydiorganosiloxane having at least one silanol group in the molecule and a viscosity at 25° C. of 5-10,000 cSt, and (B) 0.1-50 weight percent of a product obtained by reacting: (a) 1 mole of a compound of the formula: ##STR4## wherein Q 1 represents a monovalent group selected from the group consisting of hydrogen atom, --CH 3 , --CH 2 CH 2 NH 2 and --CH 2 CH 2 NHCH 2 CH 2 NH 2 , R 1 represents a divalent hydrocarbon group having 1-4 carbon atoms, R 2 and R 3 each represent a monovalent hydrocarbon group having 1-4 carbon atoms and a represents an integer of 0 or 1, with (b) 0.5-3.0 mole of a compound of the formula: ##STR5## wherein Q 2 represents an epoxy group-containing group selected from the group consisting of glycidoxy and epoxycyclohexyl groups, R 4 represents a divalent hydrocarbon group having 2-4 carbon atoms, R 5 and R 6 each represent a monovalent hydrocarbon group having 1-4 carbon atoms and b represents an integer of 0 or 1, with (2) 1-50 weight percent of a compound of the formula: ##STR6## wherein R 7 and R 8 may be the same or different and each represent a substituted or unsubstituted hydrocarbon group having 1-50 carbon atoms and n represents an integer of at least 3, in the presence of: (3) 0.1-20 weight percent of a quaternary ammonium salt surfactant, and (4) 20-90 weight percent of water.
Claim 2
Dependent Claim 264 words
A silicone emulsion composition obtained by emulsion-polymerizing: (1) 0.1-60 weight percent of a reaction product of: (A) 50-99.9 weight percent of a polydiorganosiloxane having at least one silanol group in the molecule and a viscosity at 25° C. of 5-10,000 cSt, and (B) 0.1-50 weight percent of a product obtained by reacting: (a) 1 mole of a compound of the formula: ##STR4## wherein Q 1 represents a monovalent group selected from the group consisting of hydrogen atom, --CH 3 , --CH 2 CH 2 NH 2 and --CH 2 CH 2 NHCH 2 CH 2 NH 2 , R 1 represents a divalent hydrocarbon group having 1-4 carbon atoms, R 2 and R 3 each represent a monovalent hydrocarbon group having 1-4 carbon atoms and a represents an integer of 0 or 1, with (b) 0.5-3.0 mole of a compound of the formula: ##STR5## wherein Q 2 represents an epoxy group-containing group selected from the group consisting of glycidoxy and epoxycyclohexyl groups, R 4 represents a divalent hydrocarbon group having 2-4 carbon atoms, R 5 and R 6 each represent a monovalent hydrocarbon group having 1-4 carbon atoms and b represents an integer of 0 or 1, with (2) 1-50 weight percent of a compound of the formula: ##STR6## wherein R 7 and R 8 may be the same or different and each represent a substituted or unsubstituted hydrocarbon group having 1-50 carbon atoms and n represents an integer of at least 3, in the presence of: (3) 0.1-20 weight percent of a quaternary ammonium salt surfactant, and (4) 20-90 weight percent of water.
Claim 3
Dependent Claim 17 words

Claim 5
Dependent Claim 21 words
A composition according to claim 1 wherein the emulsion polymerization is carried out in the further presence of a nonionic surfactant.
Claim 6
Dependent Claim 19 words
A composition according to claim 1 wherein the emulsion polymerization is carried out using potassium hydroxide as the catalyst.
