Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
43 words
A composition comprising inorganic oxide particles containing on their surfaces a silane, its hydrolyzates or resulting condensate, which silane possesses at least two to about three hydrolyzable groups bonded to the silicon thereof and an organic group which contains a polyalkylene oxide group.
Claim 2
Dependent Claim
43 words
A composition comprising inorganic oxide particles containing on their surfaces a silane, its hydrolyzates or resulting condensate, which silane possesses at least two to about three hydrolyzable groups bonded to the silicon thereof and an organic group which contains a polyalkylene oxide group.
Claim 3
Dependent Claim
22 words
The composition of claim 1 wherein the amount of silane is from about 0.25 to about 90 weight percent of the composition.
Claim 4
Dependent Claim
23 words
The composition of claim 2 wherein the amount of the silane is from about 0.5 to about 5 weight percent of the composition.
Claim 5
Dependent Claim
88 words
The composition of claim 1 wherein the silane has the following general formula: R.sup.II (OR.sup.I).sub.a ORSiX.sub.3 wherein R can be any divalent organic group which is either oxygen or carbon bonded to the silicon atom, R I is one or more 1,2-alkylene groups each containing at least 2 carbon atoms and typically not more than about 4 carbon atoms; R II is hydrogen, alkyl, acyloxy or an organofunctional group; a is a number having a value of from 4 to about 150; and X is a hydrolyzable group.
Claim 6
Dependent Claim
18 words
A composition as claimed in claim 4 wherein a has a value of from 4 to about 120.
Claim 7
Dependent Claim
72 words
The composition of claim 4 wherein the silane is coreacted or comixed with a different silane, as encompassed by the following formula: R.sup.3.sub.n (SiX.sub.4-n).sub.b or the cohydrolyzate or the cocondensate of such different silane with the silane, wherein R 3 is an organic radical whose free valence is equal to the value of b, X is as defined above, n is equal to 0 or 1 and b is a positive number.
Claim 8
Dependent Claim
14 words
A resin or plastic composition containing the treated inorganic oxide particles of claim 1.
