Abstract
A compatibilizer for the graft reaction of polypropylene to maleic acid anhydride in order to increase high graft rate and preventing degradation of polypropylene features use of oleic acid as the second monomer to increase the graft rate of maleic acid anhydride to 3-5 %.
Description
The invention belongs to polymeric material field, particularly a kind of preparation of promoting agent for graft copolymerization of polypropylene with maleic anhydride.
At present, the report of domestic relevant polypropylene grafted modification is a lot, in the polypropylene grafted maleic anhydride process, selects for use acrylic acid, methyl methacrylate, styrene etc. to improve percent grafting as second grafted monomers, but serious at the process of grafting degradation of polypropylene, and percent grafting is not high yet.
The purpose of this invention is to provide a kind of percent grafting height, degradation of polypropylene is little, polarity is big promoting agent for graft copolymerization of polypropylene with maleic anhydride.
The object of the present invention is achieved like this: with 0.1-1 part cumyl peroxide, 0.1-1 the diphenyl peroxide formic acid of part, 1-10 part maleic anhydride, 1-10 part oleic acid, 80-90 part polypropylene stirred 5 minutes at high-speed mixer, made mixing of materials even, in double screw extruder, carry out melting graft reaction, reaction temperature is between 180-200 ℃, carries out water-cooled, drying, pelletizing then, promptly gets promoting agent for graft copolymerization of polypropylene with maleic anhydride.
The invention has the advantages that with oleic acid can reach 3-5% as the percent grafting that second monomer improves maleic anhydride, and reduced polyacrylic degraded, polyacrylic melt index is constant before and after the reaction.
Claims (1)
1, a kind of polypropylene grafted rare maleic anhydride compatilizer is that material mixes through high-speed mixer, in double screw extruder, carry out melting graft reaction, carrying out water-cooled, drying, pelletizing then makes, its characteristic formula is: 0.1-1 part cumyl peroxide, 0.1-1 the diphenyl peroxide formic acid of part, 1-10 part maleic anhydride, 1-10 part oleic acid, 80-90 part polypropylene.
