<p>A preexpanded polyolefin resin particle which comprises a base resin prepared by incorporating 0.1 to 10 parts by weight of a polymer having carboxyl groups in 100 parts by weight of a polyolefin resin and which has a cell diameter of 200 to 500 νm. Moldings formed by the expansion molding of the preexpanded particles in a mold show a lower shrinkage rate and a smaller deformation, thus showing a good and attractive appearance and being producible in an enhanced yield.</p> |
