くない。The above components A and B, polycarbonate and polyolefin, can be blended in any proportion, but their mechanical properties,
Considering the balance between moldability and heat resistance, 90 to 90 parts by weight of polycarbonate should be mixed with 9 parts by weight of polyolefin.
It is appropriate to mix it in a ratio of 0 to 10 parts by weight. If the amount of polycarbonate is less than 10 parts by weight, the molding processability of the resulting resin composition is good, but the heat resistance and mechanical properties are poor, which is undesirable. If the amount of polycarbonate is 90 parts by weight or more, the heat resistance of the resulting resin composition is poor. Although it has good properties and mechanical properties, it is not preferred because its moldability is poor.
