Abstract:
The invention provides a coating agent for a flow passage which comprises a copolymer containing a recurring unit which contains an organic group of the formula (a) wherein U a1  and U a2  are defined herein, and a recurring unit which contains an organic group of the formula (b) wherein U b1 , U b2 , U b3 , and An −  are defined herein. The invention also provides a flow passage device having the coating agent for a flow passage on at least part of an inner surface of a flow passage, a platelet-producing flow passage device and a method for manufacturing the same.

Claim (Index 3):
The coating agent for a flow passage according to  claim 1 , wherein the copolymer comprises recurring units of the following formulae (a1) and (b1): wherein T a  and T b  each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms; Q a  and Q b  each independently represent a single bond, an ester bond or an amide bond; R a  and R b  each independently represent a linear or branched alkylene group having 1 to 10 carbon atoms which may be substituted by a halogen atom; U a1 , U a2 , U b1 , U b2  and U b3  each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 5 carbon atoms; An \u2212  represents an anion selected from the group consisting of a halide ion, an inorganic acid ion, a hydroxide ion and an isothiocyanate ion; and m represents an integer of 0 to 6.
