Rheological, mechanical and morphological properties of poly(methyl methacrylate)/poly(ethylene terephthalate) blend with dual reactive interfacial compatibilization

Abstract

SbstractIn this work, the rheological, mechanical and morphological behavior of immiscible blend poly (methyl methacrylate) with elastomeric particles (PMMA elast ) and post-consumer poly (ethylene terephthalate) (PET) with and without the use of the interfacial compatibilizer poly (methyl methacrylate-co-glycidyl methacrylate-co-ethyl acrylate) (MGE) was studied. The significant increase in torque presented in rheological analyses has shown a indication of chemical reactions between the epoxy group of MGE with end groups of PET chains and also with the elastomeric phase of PMMA elast . The increased concentration of PET yielded an increase in maximum strength and elasticity modulus and a decrease in elongation at break. The PMMA elast /PET binary blend (50/50 wt%) and PMMA elast /PET/MGE compatibilized blend (65/30/5 wt%) showed pronounced results in elongation at break compared to PMMA elast , whereas, in the first results were due to the evidence of a co-continuous morphological structure and in the second, due to the efficiency of the dual reactive interfacial compatibilization of PMMA elast /PET blends. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) analyses showed that PMMA elast /PET/MGE blends exhibit complex phase morphology due to the presence of elastomeric particles in the PMMA elast copolymer and in the use of MGE terpolymer.

A Microrheological Study of Poly(Methyl Methacrylate) Elastomer/Poly(Ethylene Terephthalate) (PMMAelast/PET) Blends

“…(30 wt% of PET). This corroborates with the efficiency results of the dual reactive interfacial compatibilization of PMMA elast /PET blend with MGE 16 . According to other researchers 25 , the compatibilization mechanism involves the induction of interfacial interactions between the components of the polymer blend.…”

“…Poly (methyl methacrylate) with elastomeric particles (PMMA elast ) 13,14 and PET have complementary properties 15 ; hence, variations in the composition of their mixtures alter their structural and morphological characteristics. Earlier studies of PMMA elast /PET immiscible polymer blends conducted by Reinaldo et al 16 revealed synergistic properties that can be used in specific applications. As for the efficiency of compatibilization, the authors found evidence of dual reactivity between MGE and PET, and also with PMMA elast , due to the presence of the elastomer phase of PMMA.…”

Influence of Morphology on Fracture Propagation of PMMAe/PC Blend in Tensile Tests at High Strain Rate

“…Due to its mechanical improvement compared to commercial homopolymer DOI: 10.1002/masy.202000153 poly(methyl methacrylate) (PMMAh), it has high potential for several technological applications. [1][2][3][4][5][6][7] Polycarbonate (PC) is an engineering polymer used in several applications due to its excellent mechanical properties, durability, transparency and thermal resistance. [8][9][10] Study of PMMAh/PC blend has mainly focused on the development of products for applications such as gas separation membranes, storage disks and packaging, due to its improvement on optical, thermal and mechanical properties.…”

Effect of Processing Conditions on the Mechanical and Morphological Properties of Elastomeric Poly (Methyl Methacrylate)/Polycarbonate Blends

“…The physical mixing of PMMAe with PC results in a synergistic combination of properties, since the use of this type of PMMA provides a complex mixing system due to the presence elastomeric particles, which produce properties different from those observed in PMMA/PC blends. Reinaldo et al used PMMAe for the development of polymer blend containing polyethylene terephthalate and achieved a synergistic combination of rheological, mechanical, and morphological properties, enabling the use of these polymer blends for various applications.…”

“…However, some transparent and toughened PMMA materials with core‐shell particles are currently marketed as the elastomeric PMMA (PMMAe). This PMMAe is investigated in this study, and it can be used in many technological applications, partly because of its better mechanical performance than other commercial PMMA materials . Polycarbonate (PC) is used in a wide range of industrial applications due to its characteristic properties, such as high durability, excellent mechanical properties including impact strength and elastic modulus, high thermal resistance, and high transparency …”
