Preparation of High Molecular Weight Poly(urethane-urea)s Bearing Deactivated Diamines

The synthesis of poly(urethane-urea) (PUUs) bearing deactivated diamines within the backbone polymer chain is presented. Several deactivated diamines present interesting properties for several applications in the biomaterial field due to their attractive biocompatibility. Through an activation with Chloro-(trimethyl)silane (Cl-TMS) during the polymerization reaction, the reactivity of these diamines against diisocyanates was triggered, leading to PUUs Read more about Preparation of High Molecular Weight Poly(urethane-urea)s Bearing Deactivated Diamines[…]

Properties of polyurethanes derived from poly(diethylene glycol terephthalate)

The synthesis of linear and crosslinked polyurethanes based on α,ω-dihydroxypolydiethylene glycol terephthalate (PDET) is described. Prior to the preparation of these materials, a PDET polymer was obtained by conventional condensation reaction between dimethyl terephthalate and diethylene glycol, and a well-characterized fraction of PDET with number average molecular weight of 3,650 g mol−1 was chosen for the synthesis of Read more about Properties of polyurethanes derived from poly(diethylene glycol terephthalate)[…]

New insight into structure-property relationships of natural rubber and styrene-butadiene rubber nanocomposites filled with MWCNT

The outstanding properties of carbon nanotubes (CNT) have generated a lot of interest at a scientist and industrial level. CNT have attracted great attention due to their exceptional mechanical, electrical and thermal properties and also for their large aspect ratio, that is, small size and higher surface area. On this regard, CNT-rubber composites have been Read more about New insight into structure-property relationships of natural rubber and styrene-butadiene rubber nanocomposites filled with MWCNT[…]
