The multilayer foam sheet includes a polyethylene resin foam layer and a resin layer laminated on at least one of the two surfaces of the foam layer. The resin layer has a multilayer structure formed from a surface layer and an intermediate layer. Both the surface layer and the intermediate layer contain a polyethylene resin and a polymeric antistatic agent. The polymeric antistatic agent is contained in the intermediate layer at a proportion of 30-70 wt % (inclusive). The polymeric antistatic agent is contained in the surface layer at a proportion of at least 5 wt % to less than 30 wt %.

One or more of the at least one or more -olefin copolymers in the second skin layer, which may be a sealant skin layer, may include at least one ethylene-propylene-butylene polymer in combination with a plastomer and/or elastomer that contain propylene, ethylene, or a combination thereof.

Disclosed herein is a process for recycling propylene-ethylene copolymers to obtain polymers having good optical and mechanical properties, and good processability. The process comprises polymerizing propylene and ethylene under dynamic conditions; collecting the resulting copolymer powders as a mixture having an MFR.sub.2 ranging from 1.5 to 80.0 g/10 min and an ethylene content from 1.0 to 4.0 wt. %; compounding the mixture in the presence of a radical initiator and a clarifying agent; and extruding the mixture into pellets. The pellets have an MFR.sub.2 ranging from 20 to 120 g/10 min; a ratio of MFR.sub.2 pellets/MFR.sub.2 powder>1; an ethylene content ranging from 1.0 to 4.0 wt %; a crystallization temperature ranging from 100 to 125 C.; and a flexural modulus of 850 MPa or more. The disclosure also relates to the propylene-ethylene copolymer pellets thus obtained; articles made from the pellets; and the use of the pellets in injection molding applications.

A system and method for preparing micronized polymer pellets is provided. The micronized polymer pellets include a polymer resin and an antistat agent. The micronized polymer pellets are particularly useful for rotomolding applications.
