The content of (meth)acrylate having 12 to 22 carbon atoms is 5 to 60% by weight. If it is less than 5% by weight, the affinity with thermoplastic resins, particularly polypropylene resins will be low, resulting in poor compatibility and dispersibility, which is undesirable, and if it exceeds 60% by weight, the physical properties of the resin will deteriorate, which is not preferred. Further, the epoxy group-containing monomer is contained in an amount of 5 to 60% by weight. If it is less than 5% by weight, the effect as a compatibilizing agent will be reduced, and if it exceeds 60% by weight, aggregates will be formed in the resin, resulting in poor uniformity. The content of other copolymerizable i-mers is from 0 to 90% by weight, and if the content exceeds 90% by weight, the effect as a compatibilizer will decrease.

Example 4, Comparative Example 4 A polypropylene resin, a polyphenylene oxide resin, and a compatibilizer (D) were blended in the proportions shown in Table 2, and the same procedure as in Example 3 was carried out to prepare a test piece for measuring physical properties. As a result, the stability of the strands when taken off during kneading in an extruder was good, and the appearance of the injection molded product was also good.

In Example 7, the stability of strand take-up and the appearance of the injection molded product due to crosstalk in the extruder were not satisfactory, but they were improved over the comparative example. In Example 8, although it cannot be said that the physical properties of the resin were sufficient, the stability at the time of taking off the strand during mixing in the extruder was good, and the appearance of the injection molded product was also good.
