DEVELOPMENT IN SYNTHESIS AND COATING APPLICATIONS OF POLYURETHANE

ABSTRACT Polyurethanes as one of the leading elastomers are explored in academics as well as in industry. These are segmented macromolecules having alternate sequence of soft and hard segments. Structure-property correlation between these segments has been extensively reported in the literature. PUs...
