Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
17 words
A composition of matter as in claim 1 wherein the organo titanium compound is triisopropyl monooleyl titanate.
Claim 2
Dependent Claim
17 words
A composition of matter as in claim 1 wherein the organo titanium compound is diisopropyl dioleyl titanate.
Claim 3
Dependent Claim
34 words
A composition of matter as in claim 1 wherein the organo titanium compound is present in an amount ranging from 0.5 to 6 weight percent based on the dry weight of the inorganic material.
Claim 4
Dependent Claim
27 words
A composition of matter as in claim 1 wherein the inorganic material at its surface contains from about 0.1 to about 2.0 weight percent of adsorbed water.
Claim 5
Dependent Claim
14 words
A composition of matter as in claim 1 wherein the inorganic material is clay.
Claim 6
Dependent Claim
187 words
A process for providing a hydrophobic, oleophilic inorganic material which comprises reacting the inorganic material with an organo titanium compound containing at least two hydrolyzable groups and which is represented by the formula Ti(OR)mR''4 m wherein R is a hydrocarbon radical containing from one to 12 carbon atoms and R'' is OCOR'''', OR'''''', or OSiR'''' wherein R'''' is a substituted or unsubstituted hydrocarbon radical having from one to 40 carbon atoms and wherein R'''''' is a substituted or unsubstituted hydrocarBon radical having from six to 40 carbon atoms providing that R'''''' and R are not identical and wherein m is equal to 2 or 3, and wherein said inorganic material prior to reaction with said organo titanium compound contains at its surface either adsorbed water, in an amount ranging from about 0.1 to about 2 percent, weight percent, based on the filler, or reactive hydroxyl groups or both reactive hydroxyl groups and said adsorbed water, whereby the hydrolyzable groups of said compound are hydrolyzed by said adsorbed water or reactive hydroxy groups, or both, to produce a polymeric organo-titanium compound at the surfaces of said inorganic material.
Claim 7
Dependent Claim
42 words
A process as in claim 7 wherein said inorganic material prior to reaction with the organo titanium compound contains at its surface from about 0.1 to about 2.0 percent by weight of water based on the dry weight of the inorganic material.
