Abstract
Inventia se refera la un amestec de polieteri-polioli pentru spume poliuretanice flexibile care este constituit dintr-un polieter homopolimer al propilenoxidului cu indice hidroxil 50...70mg KOH/g, de preferinta 50...65 mg KOH/mg si un polieter bloccoplimer propilenoxid-etilenoxid, continînd 10...30% în greutate etilenoxid ca bloc terminal, de preferinta 10...15% în greutate, cu indice hidroxil 30...53 mg KOH/g, raportul în greutate între cei doi componenti fiind cuprins între 1:1 si 4:1, polieterul homopolimer al propilenoxidului poate constitui intermediul propoxilat în obtinerea polieterului etoxilat.
