【Abstract】 Adhesives for bonding polyeolefins with good adhesion are pred. by modifying chlorinate polypropylene with acrylic acid oracrylates in Ph Me solvents, in the presence of radical initiators. For example, 100g chlorinated poly propylene (30—40%cl)was mixed with 1.2～1.5g acrylic acid in phme, in the pr esence of peroxide initiators for 3h at 110℃ Polypropylene specimens were coated with the modified chlorinated polypropylene adhesive, allow to stand for 5—10 min. , and pressed togather. The adhesive was handened at 120℃ for 1.5h, and had shear strength 35～36 kg/cm.更多还原
