본 발명은 폴리프로필렌의 가교 방법에 관한 것이며, 상기 가교 방법은 (a) (i) 폴리프로필렌, (ii) 말레이미드-관능화된 모노-아자이드 및/또는 시트라콘이미드-관능화된 모노-아자이드, 및 (iii) 하이드로퀴논, 하이드로퀴논 유도체, 벤조퀴논, 벤조퀴논 유도체, 카테콜, 카테콜 유도체, 2,2,6,6-테트라메틸피페리디노옥시(TEMPO), TEMPO 유도체 및 이들의 조합으로 이루어진 군으로부터 선택되는 라디칼 스캐빈저의 혼합물을 120℃ 내지 250℃ 범위의 온도에서 처리하여, 관능화된 폴리프로필렌을 형성하는 단계, 및 (b) 상기 관능화된 폴리프로필렌을 퍼옥사이드와 150℃ 내지 350℃ 범위의 온도에서 반응시키는 단계를 포함한다. Process for crosslinking polypropylene comprising the steps of (a) treating a mixture of (i) polypropylene, (ii) a maleimide-functionalized mono-azide and/or a citraconimide-functionalized mono-azide, and (iii) a radical scavenger selected from the group consisting of hydroquinone, hydroquinone derivatives, benzoquinone, benzoquinone derivatives, catechol, catechol derivatives, 2,2,6,6-tetramethylpiperidinooxy (TEMPO), TEMPO derivatives, and combinations thereof, at a temperature in the range 120-250° C. to form a functionalized polypropylene, and (b) reacting the functionalized polypropylene with a peroxide at a temperature in the range 150-350° C.
