<P>PROBLEM TO BE SOLVED: To provide a method for producing a modified propylene polymer having an excellent balance between melt tension and flowability. <P>SOLUTION: The method for producing the modified propylene polymer comprises a heat treatment step of heat-treating a mixture of 100 pts.wt. of a propylene polymer (A) with 0.01-20 pts.wt. of an organic peroxide (B) whose decomposition temperature at which the half-life thereof becomes one minute, is <120°C, by using an extruder at the temperature lower than the decomposition temperature at which the half-life of the organic peroxide (B) becomes one minute. <P>COPYRIGHT: (C)2013,JPO&INPIT |
