2.1 yon polymère ak yon mwayèn pwa moléculaire nan yon ran de 1,000 10,000 Daltons, ki gen oligomers de moléculaire pwa de mezi pi ba pase 500 Daltons nan kantite mwens pase 10%, oligomers pi ba pase 1,000 Daltons nan kantite mwens ke 25%. Ak polymère a pa a gen nenpòt nan byen wo konsène chimik gwoup yo pa egzanp, amines, etc..
