Poliamit

Poliamit, peptid bağları tarafından bağlanmış monomerler iceren bir polimerdir. Doğal olarak (proteinler, yun, ipek) da oluşabilirler, suni olarak (naylon, kevlar, sodyum (poli)aspertat) da yapılabilirler.

Bir asit klorid grubu veya karboksilik asit ve bir amino grubun yoğuşma reaksiyonundan amit bağı elde edilir. Kucuk molekul, (genellikle su, amonyak veya hidrojen klorid) elimine edilir. Amino grup ve karboksilik asit grubu aynı monomer uzerinde olabilir, veya biri iki amino grup ile, diğeri iki karboksilik asit veya asit klorid grubu ile iki farklı bifonksiyonel monomerden, polimer oluşabilir.
Amino asitler, tekil monomer orneklerindeki gibi, benzer molekullerle reaksiyona girip poliamit formunu alabilir.
