“…Graft polymerization can be initiated by various methods, such as high energy (γ rays and electron beams),4, 5 plasma treatment,6 ultraviolet,7, 8 chemical initiators (including graft polymerization in solution and in melt), and polymer oxidation. Methacrylic acid,9 styrene,10–13 acrylic acid,14 benzyl acrylate,15 maleic anhydride (MAH),16 glycidyl methacrylate, acryl amide,17 oxazoline,2, 18 and long‐chain unsaturated monomers19, 20 are among the monomers most commonly grafted onto polymers containing butadiene. Several articles7, 8, 14, 16, 17, 19, 20 have recently appeared on the subject of the grafting of vinyl monomers onto acrylonitrile–butadiene–styrene terpolymer (ABS).…”

ABSTRACT:The graft copolymerization of maleic anhydride (MAH) onto acrylonitrile-butadiene-styrene terpolymer (ABS) was carried out with dicumyl peroxide (DCP) and benzoyl peroxide (BPO) as the binary initiators and with styrene as the comonomer in the molten state. IR spectra confirmed that MAH was successfully grafted onto the ABS backbone. A reaction mechanism was proposed: the grafting most likely took place through the addition of MAH radicals to the double bond of the butadiene region of ABS. Influences such as the MAH concentration, the initiators and their concentrations, the reaction temperature, the rotating speed, and the comonomer concentration were studied. The results indicated that using styrene as a comonomer and DCP/BPO as binary initiators was beneficial for the graft copolymerization.

“…The impact strength of ABS-g-GMA/St decreased as the initiator concentration increased, as shown in Figure 8 , which may be explained by the grafting reaction occurring most likely in the butadiene region of ABS, and thus the contents of the butadiene region (rubber region) are decreased with increased initiator concentration, which is also reported in Rao et al ' s work [22] and Qi et al ' s work [23] . …”

The grafting copolymerization of glycidyl methacrylate (GMA) onto acrylonitrile-butadiene-styrene (ABS) terpolymer was carried out using the melt grafting process. Infrared (IR) spectra, 1 H nuclear magnetic resonance spectra, and elemental analysis results confirmed that GMA was successfully grafted onto the ABS backbone. The grafting occurred at the butadiene region of ABS, and a reaction mechanism has been proposed. The influencing factors of the reaction, such as GMA concentration, the initiator content, and the presence of GMA carrier and comonomer on the grafting copolymerization, were also studied. Results indicated that the preparation of ABSg-GMA can be carried out by melt extrusion in the presence of a GMA carrier, and a high grafting degree can be obtained when the grafting process is carried out in the presence of styrene.

“…Maleic anhydride is another important monomer for ABS grafting. Carrot et al 7 and Rao et al 8 carried out the grafting of maleic anhydride onto ABS in a molten state and in solution, respectively. Rodriguez-Gonzalez et al 9 also studied the grafting of maleic anhydride onto ABS in a Brabender mixing chamber, and they found that FTIR spectroscopy, potentiometry, and elemental analysis were all reasonable methods to determine the grafting degree of graft copolymer.…”

ABSTRACT:The graft copolymerization of undecylenic acid, oleic acid, and crotonic acid onto acrylonitrile-butadiene-styrene terpolymer (ABS) was initiated by benzoyl peroxide (BPO) in 1,2-dichloroethane solution. The infrared spectra confirmed that undecylenic acid, oleic acid, and crotonic acid were successfully grafted onto the ABS backbone. The grafting occurred at the butadiene region of the ABS. The grafting degree increased with increasing monomer concentration, but it decreased after monomer concentration, reaching 0.30 mol/L in undecylenic acid and oleic acid systems. The grafting degree increased rapidly with increasing initiator concentration, but slowed down at about 0.012 mol/L of initiator concentration. The grafting degree decreased considerably with increasing ABS concentration; however, the total amount of grafted monomer increased. Increasing reaction time and temperature led to an increase in grafting degree. The chain length of the monomer has a great influence on grafting. The grafting degree decreases with increasing the chain length due to a steric hindrance and monomer cage effect, which is in agreement with activation energy calculation. The overall activation energy of crotonic acid, undecylenic acid, and oleic acid systems are 118, 122, and 134 kJ/mol, respectively.
