ABSTRACT:
Polyolefin particles having a halogenated surface region, which are prepared by irradiating ultraviolet rays to an aqueous dispersion of polyolefin particles in the presence of a halogen gas. The polyolefin particles having a halogenated surface region have an improved property of retaining volatile blowing agents and can provide expandable particles having an improved storability in the open state.
