Role of homopolymerization in the peroxide‐catalyzed reaction of maleic anhydride and polyethylene in the absence of solvent

Maleic acid grafted low density polyethylene for thermally sprayable anticorrosive coatings

“…Some of the radicals present in powders participate in grafting on LDPE. In this study, an attempt was made to graft MAc directly to avoid additional step of hydrolysis of MAn to MAc as done in conventional methods [11][12][13][14][15][16]. LDPE-g-MAc, thus obtained was characterized by various techniques.…”

“…Rangnathan et al [14] reported that performance of maleic anhydride graft modified polymers in adhesion and compatibilization can be expected to depend on the chemical nature and microstructure of the graft. Gaylord et al [15][16][17] reported formation of single and oligomeric grafts during grafting of maleic anhydride onto polyolefins. In addition to these grafts, bridges consisting of single and oligomeric maleic anhydride units between polymer chains were proposed.…”

“…Considerable studies have been carried out on maleic anhydride [13][14][15][16][17][18] grafting of polyethylene. But authors have not come across any reported work where maleic acid (MAc) has been taken as starting material for grafting on low density polyethylene (LDPE).…”

FTIR and thermal studies on esters grafted HDPE

“…Grafting of undecylenic acid onto ethylene octane copolymer under molten condition was reported by He et al 7 Melt grafting of N-carboxyl maleamic acid onto LLDPE was reported by Ciolino et al 8 . Gaylord and Mehta et al 9 studied the melt grafting process of PE with maleic anhydride monomer. Many experimental conditions including initiator, temperature and time, etc, were studied to determine % of cross linking and degradation that accompanies the grafting reaction 10 .…”

Degradation of Different Types of Polyethylene Using for Lining System Exposed to Hydrochloric Acid Solution

“…A study on thermal expansion of maleic anhydride and ethylene-propylene-diene ter-polymer modified mid-density polyethylene MDPE showed that there is no significant change in thermal expansion for the MDPE blended with a small additional amount of the additives in comparison with the originals 9 . Gaylord et al [10][11][12] reported that single oligomeric grafts formed during the grafting of maleic anhydride onto polyolefins. Adhesion and compatibilization of maleic anhydride grafted polymers can be expected to depend on the chemical nature and microstructure of the graft 13 .…”
