Abstract
In this work, blends of monomer-cast polyamide 6 (MCPA6) and polyurethane (TPU) were prepared by in situ anionic ring-opening polymerization using caprolactam as the monomer and sodium hydroxide (NaOH) as the initiator. TPU degraded under weakly alkaline conditions to form an isocyanate group, which acted as a macromolecule activator to initiate the growth of the MCPA6 chain, and the formation of TPU-co-MCPA6 copolymer in this system, which improves the compatibility between MCPA6 and TPU. The MCPA6/TPU blends were tested for conversion, viscosity, and mechanical properties, and their structures and thermal properties were analyzed and evaluated by characterization techniques such as Fourier transform infrared spectroscopy, differential scanning calorimetry, and scanning electron microscopy.
期刊介绍：
Journal of Polymer Research provides a forum for the prompt publication of articles concerning the fundamental and applied research of polymers. Its great feature lies in the diversity of content which it encompasses, drawing together results from all aspects of polymer science and technology.
As polymer research is rapidly growing around the globe, the aim of this journal is to establish itself as a significant information tool not only for the international polymer researchers in academia but also for those working in industry. The scope of the journal covers a wide range of the highly interdisciplinary field of polymer science and technology.
