“…Polymers chemically modified with maleic anhydride (MA) are often used in the compatibilization of polyamidebased materials due to the high probability of in-situ reactions between MA and the amine end-groups of PA [11][12][13] . In our previous work 10 , we demonstrated the utility of methyl methacrylate-co-maleic anhydride (MMA-MA) in the compatibilization of PA6/ABS blends.…”

“…17 Of the variables that influence toughening, the particle size of the rubber dispersed phase was considered to be the main parameter. 2,5,11,18,19 However, more recently, the mean inter-particle distance between two neighboring particles (τ) has been proposed 14 as the factor that controls super-toughness, that should appear when τ is below a critical value (τ c ). Firstly, it was proposed that τ c was a characteristic of a given matrix, 14,17,20 but subsequent studies demonstrated that there are extrinsic parameters 10,[20][21][22][23][24] such as the test temperature, strain rate and mode of deformation that influence the value of τ c .…”

“…The improvement obtained is significant, but recently much higher increases leading to so-called super-toughness, have been attained by compatibilization, [3][4][5][6] for instance, with maleic anhydride, epoxy or compounds with amine groups. Thermoplastics for which super-toughness was achieved include poly(butylene terephthalate) (PBT), 3,[7][8][9][10] polyamides, 5,[11][12][13][14][15] amorphous copolyester, 6 polyoxymethylene, 10 poly-(phenylene sulfide), 10 poly(vinyl chloride) 16 and high density polyethylene. 17 Of the variables that influence toughening, the particle size of the rubber dispersed phase was considered to be the main parameter.…”

“…O comportamento observado nas blendas estudadas, onde houve um aumento do tamanho de partícula quando adicionado o compatibilizante com alta concentração de anidrido maleico (5 e 10%MA), está relacionado ao fato das blendas reativas terem um aumento significativo na viscosidade do fundido em relação à mistura não compatibilizada, pois a reação de graftização pode alterar a razão de viscosidade [13,14] . Favis et al [15] obser- vou limites inferiores e superiores na razão de viscosidade em blendas PP/PC, no qual a deformação e quebra das partículas ficam mais difíceis.…”
