Resumen de: PL449460A1

Przedmiotem zgłoszenia jest termoplastyczny materiał z chitozanem, który zawiera 40% do 85% m/m polikaprolaktonu o masie cząsteczkowej od 50 000 do 90 000 Da, 5% do 50% m/m chitozanu, 2% do 10% m/m poliolu, który wybiera się z grupy obejmującej: alifatyczne nasycone alkohole dihydroksylowe o długości łańcucha węglowego C2-C8 oraz polieterole o masie cząsteczkowej ≤ 200, 2% do 5% m/m produktu estryfikacji oligomerów kwasu mlekowego z etanolem o liczbie kwasowej ≤ 80 mg KOH/g, o średniej masie cząsteczkowej ≤ 600. Zgłoszenie obejmuje także sposób wytwarzania termoplastycznego materiału z chitozanem, który polega na tym, że do wyposażonego w ślimaki urządzenia wprowadza się 40% do 85% m/m polikaprolaktonu o masie cząsteczkowej od 50 000 do 90 000, 5% do 50% m/m chitozanu, 2% do 10% m/m diolu, który wybiera się z grupy obejmującej: alifatyczne nasycone alkohole o długości łańcucha węglowego C2-C6 i polieterole o masie cząsteczkowej ≤ 200, 2% do 5% m/m produktu estryfikacji oligomerów kwasu mlekowego z etanolem o liczbie kwasowej ≤ 80 mg KOH/g i średniej masie cząsteczkowej ≤ 600. Całość miesza się, w temperaturze od 70°C do 100°C, a prędkość obrotowa ślimaków wynosi od 40 do 90 rpm.
