<p><P>PROBLEM TO BE SOLVED: To provide a method of producing a polyolefin resin foam, by which the polyolefin resin foam having high thickness accuracy can be obtained. <P>SOLUTION: The method of producing the polyolefin resin foam includes the steps of: promoting the reaction of a material comprising 100 pts.mass of a chain polyolefin and 1-40 pts.mass of a cyclic polyolefin to obtain a reactant having a gel fraction of 10-60 wt.%; and foaming the reactant by using, as a foaming agent, a physical foaming agent that changes from a liquid to a gas at 25°C or that is a liquid having a boiling point of≤120°C, thus obtaining the polyolefin resin foam having density of 25-500 kg/m<SP POS="POST">3</SP>. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
