Abstract
Two plastics which were heretofore impossible to combine, can be combined with each other if the one to be added is converted to a porodin gel by heating the same at a temperature of at least 180.degree. C. with a substance that does not dissolve the polymer, and then cooling to below 120.degree.. The porodin gel can then be easily admixed with the other plastic material in an amount of 1 to 50% by weight, preferably 5 to 20% by weight based on the weight of the modified plastic material. Examples are the incorporation of polyethylene or polypropylene or polymethyl methacrylate in polyvinyl chloride, or the incorporation of polystyrene in polypropylene, or the incorporation of polymethyl methacrylate in polyethylene.
