Abstract
Abstract The composition of crystalline 1-butene polymer comprising: (a) a crystalline 1-butene polymer containing a 1-butene component as a main component, and (b) a radical-treated crystalline olefinic polymer having (1) a boiling p-xylene-insoluble content of 30% by weight at most and (2) the relation satisfying the following expression TcCL-TcO>/=1 wherein TcCL is the crystallization temperature ( DEG C.) of the radical-treated crystalline olefinic polymer, and TcO is the crystallization temperature of the crystalline olefinic polymer before the radical treatment, and (c) the proportion of the radical-treated crystalline olefinic polymer (b) being 0.2 to 100 parts by weight per 100 parts by weight of the crystalline 1-butene polymer (a).
