Patent ID: 7094827

Claim:
A thixotropic agent comprising as components from 0.1 to 30% by weight of at least one ethylene terpolymer wax synthesized from from 80 to 99.9% by weight of ethylene, from 0.1 to 20% by weight of at least two comonomers comprising as first comonomer from 1 to 99% by weight of at least one C 3 –C 12 alkenecarboxylic acid and as second comonomer from 99 to 1% by weight of at least one ester of the formula I where R 1 is selected from the group consisting of hydrogen, C 1 –C 10 alkyl, C 3 –C 12 cycloalkyl, and C 6 –C 14 aryl and R 2 is selected from the group consisting of C 1 –C 10 alkyl, C 3 –C 12 cycloalkyl, and C 6 –C 14 aryl, from 5 to 70% by weight of at least one first solvent incompatible with the ethylene terpolymer wax, and from 5 to 85% by weight of at least one second solvent compatible with the ethylene terpolymer wax and with said first solvent(s).
