The Morphology and Structure of Multi-component Polyurethane Macroporous Adsorbents

Abstract

Abstract: The polyurethane macroporous segmented copolymers were synthesized by two step polymerization.The products were investigated by FTIR, DSCand SAXS techniques .The results show that the structure of macroporous adsorbents is as expected.As the specific surface area and pore diameter data are concerned, they have comparable physical properties to commercial porous polymers.The morphology of polyurethane macroporous copolymer is three domain structures, which would be beneficial to the adsorption behavior and selectivity of adsorbents.

Key words: Polyurethane, Multi-component, Macroporous adsorbents
