Abstract
A polyolefin resin composition comprising (a) 100 parts by weight of a polyolefin resin and (b) 0.05 to 1 part by weight of beads of a crosslinked polymer comprising (1) 5 to 99% by weight of a radically polymerizable monomer unit represented by the general formula (A): ##STR1## wherein R.sub.1 is hydrogen or a hydrocarbon group having 1 to 5 carbon atoms and R.sub.2 is a hydrocarbon group having 5 to 30 carbon atoms, (2) 0 to 94% by weight of a radically polymerizable monomer unit other than the monomer unit of the general formula (A), and (3) 1 to 20% by weight of a crosslinkable monomer unit, said crosslinked polymer beads having a critical surface tension of 40 dyne/cm or less.
