Applications of the fluorine conversion monomer content parents crocking Characteristic copolymer in order to give waterproof Characteristic to the leather

摘要

(57) Abstract As for this invention, the configuration unit which is repeated,(if in formula, R _f displays fluorine conversion alkyl group which at least possesses 3 carbon atoms, Q and Q '' display organicity join basis or chemical bond in the respective independence, R¹ and R² hydrogen or displays C₁ - C₄ alkyl groups in the respective independence, R _h has 8 carbon atoms at least and requires hydrocarbon group which contains 1 - 3 substituents is displayed.)The parents crocking Characteristic copolymer which includes the configuration unit which and at least includes 1 carbon acid radicals or those salts and repeats is offered. This invention offers also the manner which produces the above-mentioned parents crocking Characteristic copolymer. The parents crocking Characteristic copolymer, using for leather treatment, can offer waterproof Characteristic to the leather.
