Composition of polymer, its preparation, its further processing in containers especially containers of storage or transport and disposable containers as well as the use of phenols to protect the contents of the container in materials containing plastic, particularly in disposable containers made from it.

摘要

A process for preparing a container for handling a household waste material which involves molding a household waste container from a plastic batch material containing 0.1 to 10% by weight of at least one phenol biocide selected from the group consisting of 5,5'-dichloro-2,2'-dihydroxydiphenyl methane, 3,5,3',5'-tetrachloro-4,4'-dihydroxydiphenyl methane, 3,5,6,3',5',6'-hexachloro-2,2'-dihydroxydiphenyl methane, 5,5'-dichloro-2,2'-dihydroxydiphenyl sulfide, 2,4,5,2',4',5'-hexachloro-dihydroxydiphenyl sulfide, 3,5,3',5'-tetrachloro-2,2'-dihydroxydiphenyl sulfide, and 2,4,4'-trichloro-2'-hydroxydiphenyl ether to form the container with an inner and an outer co-extruded layer wherein the phenol is applied on a co-extruded layer forming the surface of the inner co-extruded layer.
