Acaricidal resin composition containing spiro cyclopropane-1,-1'- indene!- 2-carboxylic acid, 3,3-dimethyl-, -cyano-m-phenoxybenzyl ester

摘要

The invention is novel acaricidal resin compositions containing spiro cyclopropane-1,1'-indene!2-carboxylic acid, 3,3-dimethyl- , -cyano- m-phenoxybenzyl ester. More particularly, this invention relates to flexible collars for controlling ticks on companion animals prepared from novel dry blended polyvinyl chloride resin compositions containing spiro cyclopropane-1,1'-indene!-2-carboxylic acid, 3,3- dimethyl-, -cyano- m-phenoxybenzyl ester and 15% to 25%, by weight, of a selected plasticizing agent.
