PURPOSE:To obtain the title composition excellent in moldability and appearance, comprising an unsaturated acid-modified PP, a surface-treated glass fiber, a specified nucleator and an organic peroxide radical initiator. CONSTITUTION:0.05-1wt.% metal montanate (e.g., sodium montanate) as a nucleator and 0.01-0.1wt.% organic peroxide radical initiator (e.g., dicumyl peroxide) are added to 100pts.wt. mixture of 50-95wt.% mixture of 1-50wt.% unsaturated acid-modified PP (e.g., maleic anhydride-modified PP) with 99-50wt.% PP with 50-5wt.% 3-5mm-thick glass fiber surface-treated with, e.g., a silane coupling agent.
