Synthesis and Structure of Grafted Copolymers of Acrylic Acid and Low Molecular Weight Polyethylene

Structure and properties of compositions of linear low‐density polyethylene with starch

“…The synthesis of graft copolymers with molar ratios of LMP:AA = 90:10 (LMP‐g‐AA 1) and 60:40 (LMP‐g‐AA 2) (Table 1) was performed by the radical mechanism in o ‐xylene as the solvent at a temperature of 95°C under a nitrogen atmosphere using a benzoyl peroxide initiator and is described in detail in Reference 15. To determine the composition of the grafted copolymers, the carboxyl group content was analyzed by titration with an alcohol solution of caustic potassium with phenolphthalein as an indicator.…”

“…Polyethylene wax modified with polar compounds has also been used to improve the compatibility between polyethylene and starch 14 . Previously, we synthesized copolymers of AA grafted onto low‐molecular‐weight polyethylene (LMP) and demonstrated the possibility of using them as compatibilizers in high‐pressure polyethylene compositions with starch 15,16 …”

“…14 Previously, we synthesized copolymers of AA grafted onto low-molecular-weight polyethylene (LMP) and demonstrated the possibility of using them as compatibilizers in high-pressure polyethylene compositions with starch. 15,16 This study aimed to obtain compositions of linear low-density polyethylene (LLDPE) with starch using grafted copolymers of LMP and AA as compatibilizers and conduct structural and physicomechanical investigations of the obtained compositions.…”

Functionalization of Low-Molecular-Weight Polyethylene by Melt Grafting of Maleic Anhydride for Using as a Compatibilizer

“…[23][24][25] However, one of its disadvantages is the high hydrophobicity due to the lack of reactive functional groups on the main chain. To improve its properties for the use, PEW is modified with various methods, 26 including functionalization with acrylic acid, maleic anhydride and others, 27,28 and was used to expand the adhesion properties of ultrahigh-molecular-weight polyethylene 29 for chemical surface modification of fillers, in particular, calcium carbonate particles. 30 Functionalized low-molecular-weight polyolefin (in particular, polyethylene wax) is of interest for use as a compatibilizer.…”
