  • Novel segmented copolymers containing free hydroxyl groups and method of preparing the same
    Patent number: 4038223
    Abstract: Novel segmented copolymers containing free hydroxyl groups and comprising hard and soft segments, the hard segments comprising polyhydroxy compounds containing two primary hydroxyl groups and at least two secondary hydroxyl groups, and the soft segments comprising low molecular weight polyesters or polyethers having terminal isocyanate groups the hard and soft segments being linked to each other at the primary hydroxyl groups and the isocyanate groups, the copolymer being substantially free of cross linking and containing free hydroxyl groups. The segmented copolymers are produced by reacting the low molecular weight polyether or polyester containing terminal isocyanate groups with the polyhydroxy compound, for example a disaccharide or sugar alcohol, in an N-ethylpyridinium chloride melt.
