Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
130 words
Sulfur substituted norbornyl substituted compounds characterized by having present therein the structure: ##STR86## wherein the free valences of the silicon atom are bonded to one or more monovalent hydrocarbon groups and hydrolyzable groups, R is one of the polyvalent cycloaliphatic hydrocarbon radicals characterized as follows: ##STR87## x has the value of 2 or 3; provided that when x is 2 each sulfur atom is bonded to hydrogen to form a mercaptan, and when x is 2, the two mercaptans are attached to separate carbon atoms and such carbon atoms are adjacent to one another, and when x is 3, the sulfur atoms form a trisulfide wherein each sulfur atom is bonded to another sulfur atom and the terminal valences of the trisulfide are bonded to vicinal carbon atoms of R.
Claim 2
Dependent Claim
