Dressing materials applied in orthopedic and traumatic injuries.
Part II. Urethane quasiprepolymers as chemically reactive
polyurethane-fabric composite dressing material components
Polimery 2001, No 10, 715
SummaryCharacteristic data are given on principal starting material groups (diisocyanates, oligoether oligools, oligoestrols, catalysts) used to synthesize isocyanate groups-carrying urethane-type quasiprepolymers to serve as water-curable chemically reactive components of polyurethane-fibrous substrate composites. Authors' own studies are summarized, concerned with curing of quasiprepolymers (Tables 1-5) and of polyurethane-knitted fabric composites based on these quasiprepolymers (Tables 6-9) in relation to catalyst type and catalyst quantity. Eight catalysts were examined; di(diethylene morpholine) ether proved to be the best catalyst.
