Brittle–ductile transition behavior of poly(ethylene terephthalate)/poly(ethylene-octene) blend: the roles of compatibility and test temperature

Effect of Poly(acrylic acid)-Modified Poly(ethylene terephthalate) on Improving the Integrated Mechanical Properties of Poly(ethylene terephthalate)/Elastomer Blend

“…1−4 Unfortunately, the raw PET resin has two serious shortcomings, that is, poor impact resistance and low crystallization rate, 5,6 which limits its application as an engineering plastic. 7 Therefore, the research and development on the fabrication of PET engineering plastic through blending PET with various toughening agents is very necessary, practical and valuable. 8 However, PET is thermodynamically immiscible with most toughening agents currently used in research works or practical applications due to the inner chemical structure feature, resulting in the poor dispersibility of the toughening agent phase in PET matrix.…”

“…As one of the most important synthetic polymer materials in current world, poly­(ethylene terephthalate) (PET) has been applied in a wide range of areas including textile fabric, package, biomaterials, and so forth due to its good mechanical strength, thermostability, and radiation resistance. − Unfortunately, the raw PET resin has two serious shortcomings, that is, poor impact resistance and low crystallization rate, , which limits its application as an engineering plastic . Therefore, the research and development on the fabrication of PET engineering plastic through blending PET with various toughening agents is very necessary, practical and valuable …”

Effects of ethylene‐octene copolymer (POE) on the brittle to ductile transition of high‐density polyethylene/POE blends

“…The matrix cannot sufficiently crazed into shear band yielding. In blends [33] and particle filled composites, [34] the phase structure affects the matrix function. This is different from the observation for single component polymers.…”

A stable amphiphilic hybrid nanoparticle compatibilizer constructed from polyhedral oligomeric silsesquioxane (POSS) for immiscible thermoplastic polyurethane/methyl vinyl silicone elastomer (TPU/MVQ) blends

“…The compatibility of TPU/MVQ blends is very poor, and the addition of some compatibilizers is an effective way to solve this problem, which can also increase the interfacial adhesion and optimize the morphology of TPU/MVQ blends. [9][10][11][12][13][14][15] In early studies, the compatibilizers of TPU/MVQ blends mainly included some block copolymers, 16,17 graft copolymers [18][19][20][21] and homo-copolymers, 10 such as the polydimethylsiloxane-polybutadiene-polyurethane triblock copolymer (PU-PB-PDMS), 22 the homo-copolymer of ethylene and methyl acrylate (EMA), 10 and the polyurethane-polysiloxane copolymers (PU-co-PSi). 9 However, the molecular chains of these copolymer compatibilizers are prone to curling and folding, and then form micelles and migrate into one phase during the blending process.…”
