。[0015] In this way, Examples 1 to 10 of the present invention are
The reason why the heat deformation temperature was higher than that of Comparative Examples 1 to 3 is considered to be as follows. That is, the carboxylic acid group contained in the modified polypropylene resin and the maleimide group contained in the maleimide-modified ABS react or ionicly bond with the amino groups in the amino group-containing compounds A and B as compatibilizers, respectively, and the polypropylene This is presumed to be due to improved interfacial bonding between the resin and maleimide-modified ABS. Moreover, regarding bending strength and bending elastic modulus, there is no significant difference between Examples 1 to 10 and Comparative Examples 1 to 3. In addition, the Izod impact strength of Examples 1 to 10 is slightly lower than that of polypropylene alone (Comparative Example 1),
Furthermore, it shows a high value. This indicates that the polypropylene resin composition of the present invention maintains the excellent mechanical strength of conventional polypropylene resins.
