混錬する方が効率的である。2. Description of the Related Art Similar resins, such as non-polar resins or polar resins, are easily melted and mixed, but non-polar resins and polar resins, such as polyolefin resins and vinyl chloride resins, are mixed with a conventional processing kneader. Cannot be dispersed uniformly. At the present time, when these mixtures are molded into final products, they are almost unusable in appearance and quality in most cases. However, although the necessity of material recycling of synthetic resins has been actively talked about recently, recovered resins are rarely of a uniform composition, and are usually a mixture of plural kinds. In order to effectively use this mixture as a resource, it may be one means to separate the mixture into the same composition. However, from the viewpoint of economy, it is more efficient to uniformly disperse and mix and knead the mixture.

実用化されている例は少ない。As a method of uniformly kneading and mixing, there is a method of mixing a copolymer of a nonpolar resin and a polar resin. However, in this method, it is often difficult to copolymerize a polar monomer and a non-polar monomer from the beginning, and even if a copolymer is obtained, there are many economical problems in terms of yield and monomer cost, and this method has been put to practical use.

実用化が困難な場合が多い。Another method is a method of forcibly adding a shear by using a special processing kneader to knead and disperse.
However, in this method, the resin tends to deteriorate due to shearing, and it is often difficult to put the resin into practical use due to discoloration, odor, smoke during processing, or the like.
