Radiation-induced grafting of binary monomers containing HALS onto polypropylene

Mechanical and Heat Shrinkable Properties of Electron Beam Irradiated Polypropylene With Bisphenol A Dimethacrylate Crosslinker

“…Several additives have been used, such as antioxidants based on hindered amines, organic phosphites, phenol type antioxidants [4], [5], and several crosslinking agents mainly based on monomers with allyl and acrylate functional groups that can engage in radical reactions by grafting onto polymer matrix after irradiation and during radiation-chemically induced processes [6], [7]. The authors of [8] have found that well known crosslinking agent triallyl cyanurate (TAC) acts as energy transfer agent.…”

Grafting dual polar monomers onto hydroperoxidized polypropylene with the assistant of supercritical carbon dioxide

“…However, its low surface energy and poor compatibility with other polar polymers impose a limit on certain applications. In the same sense, their adhesion to materials like wood, metals or reinforcing fibers requires special attention [1][2][3][4][5][6][7][8]. Grafting various monofunctional and multifunctional polar monomers onto its backbone offers an effective approach to overcome these disadvantages.…”

Synthesis and photostabilizing performance of a polymeric HALS based on 1,2,2,6,6-pentamethylpiperidine and vinyl acetate

“…The synthesis of HALS of higher molecular weight by addition or condensation copolymerizations [9][10][11] or the grafting of photostabilizers onto the preformed polymer [12][13][14][15][16] are usual strategies described by the literature to eliminate or minimize such undesirable effects. The preparation of polymeric HALS by the copolymerization of hindered amines with ethylene or propylene is also an alternative route to reduce their physical loss [17,18] .…”
