Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
98 words
A triorganometallic compound of the general formula I ##EQU52## wherein M represents tin or lead and R 1 , R 2 , and R 3 each independently represents a linear or branched aliphatic group with 1 to 16 carbon atoms, which can be saturated or singly olefinically unsaturated, the cyclopentyl-, cyclohexyl-, or phenyl group, the sum of the carbon atoms of the substituents R 1 , R 2 , and R 3 being at most 18 and wherein A represents a strongly hydrophilic group of the formula II ##EQU53## wherein n is a number from 2 to 15.
Claim 2
Dependent Claim
98 words
A triorganometallic compound of the general formula I ##EQU52## wherein M represents tin or lead and R 1 , R 2 , and R 3 each independently represents a linear or branched aliphatic group with 1 to 16 carbon atoms, which can be saturated or singly olefinically unsaturated, the cyclopentyl-, cyclohexyl-, or phenyl group, the sum of the carbon atoms of the substituents R 1 , R 2 , and R 3 being at most 18 and wherein A represents a strongly hydrophilic group of the formula II ##EQU53## wherein n is a number from 2 to 15.
Claim 3
Dependent Claim
33 words
