Maombi ya D2000
- Poly(propylene glikoli) bis(2-aminopropyl etha) ina upinzani mzuri wa alkali na maji na upinzani wa asidi wastani.Resini za epoxy zinazoponywa na polyetheramines zina sifa nzuri za umeme.Polyetheramines zina sifa za kipekee na hutumiwa katika karibu matumizi yote ya epoxy kama vile mipako, vifaa vya chungu, vifaa vya ujenzi, composites na adhesives.
- Matayarisho: muundo wa Poly(propylene glikoli) bis(2-aminopropyl etha): Kwanza, polyetha inaunganishwa kwenye kundi la acetoacetate katika ncha zote mbili na dienone au kupitia mmenyuko wa kubadilishana esta wa ethyl acetoacetate na polyether polyol, na kisha polyether iliyofunikwa. na kikundi cha acetoacetate hutiwa na amini ya msingi-msingi, amini ya alkili alkoholi au amini ya msingi ya dibasic ili kupata kiwanja cha imine chenye mnato mdogo na kikundi cha mwisho cha aminobutyrate.
