Elastomers based on NR/BR/SBR ternary rubber blend: morphological, mechanical and thermal properties
(Association of Chemical Engeneers of Serbia, 2019-01-24)
The elastomeric materials based on NR/BR/SBR ternary rubber blend were investigated. The polyisoprene (NR), butadiene (BR) and styrene butadiene (SBR) rubbers were used as network precursors and carbon black (CB) as an ...
Synthesis and characterization of pH-sensitive Saccharide modified polyurethane hydrogels – Effect of polyol, crosslinker and acid chain extender
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2021-07-10)
Biodegradable polyurethanes can be the basis for drug delivery systems that
are sensitive to external changes. pH-sensitive polyurethanes (PUs) have been
used successfully as intravaginal rings and specific drug delivery ...
