Process for preparing extruded foam bodies |
| abstract |
A process for preparing an extruded thermoplastic resin elongate foam body comprising an alkenyl-substituted aromatic resin is described. The process comprises the steps of (A) heat plastifying the thermoplastic resin; (B) adding at least one fluid blowing agent comprising at least one of 1-chloro-1,1-difluoroethane, 1,1,1,2-tetrafluoroethane and 2-chloro-1,1,1,2-tetrafluoroethane; (C) uniformly mixing the blowing agent in the resin under a pressure sufficient to prevent blowing of the resin thereby forming a blowable resin mixture; (D) extruding the mixture into a region of reduced pressure which is less than atmospheric pressure wherein the blowable resin mixture expands into a foam body; and (E) cooling the foam body. o |
