Open publisher page 0 citations

Abstract

In this paper,dual monomers maleic anhydride(MAH) and styrene(St)were used to graft onto PP.PP-g-MAH and PP-g-MAH/St were produced in high speed blender with friction heat by itself,utilizing the technique of solid phase graft copolymerization.The grafting rate and grafting efficiency are both enhanced greatly,when dual monomer used with 25% St.When the content of dual monomer is 12%,the grafting rate can reach to 2.2%.The suitable content of BPO is 6%,and adequacy reaction time is 90 min.
