Si un seul numéro est mentionné, cela signifie que le monomère est un aminoacide Alpha (ou son lactame) et que les chaînons amides dans le polymère sont tous "tête à queue". The reason for the differences is largely due to their differences in chemical structure. An important difference between Nylon 6 & 66 is mold shrinkage. To polymerize, the lactam has to break open into a linear form, and the lactam monomers end up enchained head-to-tail. Similarly for PA 510 PA 611; PA 1012, etc. During polymerization, the amide bond within each caprolactam molecule is broken, with the active groups on each side re-forming two new bonds as the monomer … Since caprolactam contains six carbon atoms and only one monomer is used, the polymer is thus designated as nylon 6. The OH group in the carboxyl group of nylon-66 condenses with the amino of 2ndmonomer and removes a water molecule through the process of condensation... Want to see the full answer?
