Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
102 words
An ectoparasiticide-containing polyurethane, comprising a hydrophobic polyurethane which cannot be swollen in water and which contains, relative to the polyurethane, 2 to 30% by weight of an ectoparasiticide, said ectoparasiticide selected from the group consisting of an insecticidally active carbamate having a vapor pressure of between about 10 -4 and 10 -6 mm Hg measured at 20° C., and an insecticidally active synthetic pyrethroid, and combinations thereof and, relative to the polyurethane, 8 to 25% by weight of a spreading agent, said speading agent selected from the group consisting of silicone oils, fatty acid esters, fatty alcohols, fatty acids and combinations thereof.
Claim 2
Dependent Claim
102 words
An ectoparasiticide-containing polyurethane, comprising a hydrophobic polyurethane which cannot be swollen in water and which contains, relative to the polyurethane, 2 to 30% by weight of an ectoparasiticide, said ectoparasiticide selected from the group consisting of an insecticidally active carbamate having a vapor pressure of between about 10 -4 and 10 -6 mm Hg measured at 20° C., and an insecticidally active synthetic pyrethroid, and combinations thereof and, relative to the polyurethane, 8 to 25% by weight of a spreading agent, said speading agent selected from the group consisting of silicone oils, fatty acid esters, fatty alcohols, fatty acids and combinations thereof.
Claim 3
Dependent Claim
30 words
An ectoparasiticide-containing polyurethane according to claim 1, characterized in that it contains, relative to the polyurethane, 5 to 20% by weight of the ectoparasiticide or of a combination of ectoparasiticides.
Claim 4
Dependent Claim
26 words
An ectoparasiticide-containing polyurethane according to claim 1 wherein the ectoparasiticide is 2-isopropoxyphenyl N-methyl carbamate, 3-phenoxy-4-fluoro-α-cyano-benzyl-2,2-dimethyl-3-[2-(4-chlorophenyl)-2-chlorovinyl]cyclopropane carboxylate, permethric acid pentafluorobenzyl ester or a mixture of said ectoparasiticides.
Claim 5
Dependent Claim
19 words
An ectoparasiticide-containing polyurethane according to claim 1, characterized in that the polyurethane has been prepared by the casting process.
Claim 6
Dependent Claim
39 words
An ectoparasiticide-containing polyurethane according to claim 1, characterized in that the polyurethane is a polyurethane which when stored in water at 20° C. for 24 hous, absorbs less than 0.5% by weight of water as a result of swelling.
