摘要

This study deals with the synthesis and the evaluation of salen Shiff based as a new class of flame retardant in thermoplastic polyurethane (TPU). Salens, imines and a polysalen were synthesized. These compounds were then incorporated in TPU as a loading as low as 10 wt%. The thermal stability as well as the fire properties of the TPU formulations were evaluated. The PCFC results showed that hydroxysalen has better properties as salen. It was also observed that the imines and the polysalen exhibit similar fire properties than salens when evaluated by PCFC and LOI.
