Title: | Structure and physical properties of segmented polyurethane elastomers containing chemical crosslinks in the hard segment | Authors: | Petrović, Zoran Javni, Ivan Divjaković, Vladimir |
Issue Date: | 30-Jan-1998 | Journal: | Journal of Polymer Science, Part B: Polymer Physics | Abstract: | Two series of segmented polyurethanes, one containing 50% soft segments and the other with 70% soft segments were synthesized. Chemical crosslinks were introduced through the hard segment in a controlled way. Chemical polyurethane networks were characterized by swelling. The effect of the degree of crosslinking on properties was examined. It was found that chemical crosslinks in the hard segment reduce the mobility of the soft phase and destroy the crystallinity of the hard phase, but they improve heat stability of the hard domains. © 1998 John Wiley & Sons, Inc. | URI: | https://open.uns.ac.rs/handle/123456789/10192 | ISSN: | 08876266 | DOI: | 10.1002/(SICI)1099-0488(19980130)36:2<221::AID-POLB3>3.0.CO;2-U |
