Abstract
Przedmiotem wynalazku jest sposób otrzymywania poli(N-winylopirolidonu) z wykorzystaniem ciśnieniowej polimeryzacji wolnorodnikowej N-winylopirolidonu (NVP) indukowanej światłem, w masie lub rozpuszczalniku, w korzystnych warunkach ciśnienia i temperatury (p i T). Sposób polega na tym, że do monomeru w postaci N-winylopirolidonu dodaje się fotoinicjator rodnikowy, to jest fotoinicjator, w którym podczas absorbcji dostarczonego światła dochodzi do rozerwania własnych wiązań i wytworzenia rodników, w stosunku wagowym fotoinicjatora do monomeru w zakresie 0,05-5% wag./wag., następnie mieszaninę reakcyjną umieszcza się w kapsule reaktora ciśnieniowego wykonanej z materiału przepuszczalnego dla promieniowania świetlnego, którą umieszcza się w komorze ciśnieniowej wyposażonej w okienka wykonane z materiału przepuszczalnego dla promieniowania świetlnego, po czym doprowadza się do odpowiednich warunków termodynamicznych, to jest do osiągnięcia temperatury w zakresie od 5 do 60°C, oraz ciśnienia w zakresie od 10 do 250 MPa, a następnie skompresowaną mieszaninę reakcyjną naświetla się światłem o długości fali w zakresie widma absorbcji zastosowanego fotoinicjatora i intensywności wystarczającej do wygenerowania rodników, przez czas niezbędny do uzyskania pożądanego stopnia przereagowania monomeru.
