Abstract
PEREZ-RODRIGUEZ, Ángel Tomás et al. Blends from nylon 6 and 11 with a polyesteramide derived from tartaric and succinic acids. Rev Cub Quim [online]. 2019, vol.31, n.3, pp. 324-335. ISSN 2224-5421.
The purpose of the work is to study the mechanical properties and compatibility of binary blends obtained from polyamide 6 and polyamide 11 with a polyesteramide derived from tartaric and succinic acids with an ester content of 10 %. We have tried to obtain a new material, combining the mechanical characteristics of commercial polyamides with the degradability of polyesteramide for use with biomedical purposes, in suture threads. The blends were prepared by melting and the compatibility was evaluated by optical microscopy. The mechanical properties of these systems were obtained by tensile tests. The mechanical characteristics of the obtained blends are diminished with respect to the average value of the components, which verifies the incompatibility observed by optical microscopy; this behavior corresponds to incompatible polymer systems, which limits its use for biomedical purposes.
Keywords : binaryblends; polyamide 6 and 11; polyesteramide; compatibility.
