Abstract:
A block copolymer having at least one polymer block (A) primarily comprising the structural unit (I) represented by the formula: ##STR7## and at least one polymer block (B) primarily comprising the structural unit (II) represented by the formula: ##STR8## (wherein R.sup.1 represents hydrogen atom or an alkyl group, R.sup.2 represents a mono-valent hydrocarbon group, and m represents an integer of 0 to 3), and having the structural unit (III) represented by the formula: ##STR9## (wherein R.sup.3 represents hydrogen atom or an alkyl group, R.sup.4 represents a saturated aliphatic hydrocarbon group with a valence of a+1, X represents a halogen atom, and a and b independently represent 1, 2 or 3) in at least one polymer block of the polymer block (A) and the polymer block (B), wherein the content of the structural unit (III) is within a range of 0.01 to 2 mol % on a basis of the total structural units in the block copolymer.
