Specifically, the present invention relates to an adhesive polypropylene resin composition suitable for adhering polypropylene to a saponified ethylene-vinyl acetate copolymer (EVAL), a polar group-containing polymer such as nylon or polyester, or a metal such as aluminum.

ている。In order to take advantage of the properties of polypropylene and provide properties that polypropylene does not originally have, such as gas barrier properties, it is widely practiced to form a multilayer structure with other polymers, especially those containing polar groups, or aluminum foil. Polypropylene and polar group-containing polymers are originally not compatible with each other, so they cannot be bonded by simply pasting them together; instead, an adhesive resin is sandwiched between them. For this purpose, a polymer in which maleic anhydride is grafted onto polypropylene is used.

入手することもできる。There are no particular restrictions on the method for producing the graft copolymer obtained by grafting an alkoxyalkenylsilane onto crystalline propylene, which is important in the present invention, and various methods are already known. Basically, this can be achieved by contact treatment of an alkoxyalkenylsilane and crystalline polypropylene under conditions in which a radical generator such as peroxide is thermally decomposed. It is common to perform melt mixing using a Henschel mixer or an extruder, and various methods have been proposed for producing crosslinked polypropylene (Japanese Patent Publication No. 48
-1711, JP-A-55-40701, JP-A-54-11
