Description
Polymerízačný stupeň ri vo vzorci I závisí od podmienok polymerizácie, najma od končentrácie monoméru a iniciátora teploty a času polyraerizácie.The polymerization stage ri in formula I depends on the polymerization conditions, in particular the concentration of the monomer and the initiator of the temperature and time of the polyraerization.
Uvedený polymér má použitie ako fosforescenčný značkovač alebo optický zjasňovač.Said polymer is used as a phosphorescent marker or an optical brightener.
PříkladExample
Monomér 1-feny1-2-[4-/2-metakryloyloxyetoxy/-fenyťj-1,2-etándión /0,6215 g/ sa rpzpustí v 1,3 ml dioxáňu, přidá sa 0,621.mg alfa,alfa'-azobisi zobutyronitrilu - AIBN /0,1 Z hm, na hmotnost monomeru/ a polymerizuje sa v inertnej atmosféře pri 55 °C 5 hodin. Polymér sa přečistí trojnásobným zrázanim z dioxánu do metanolu. Získalo sa 0,27 g slaboSltého polyméru o Mn « 156 000 v 43% výtažku.The 1-phenyl-2- [4- (2-methacryloyloxyethoxy) -phenyl] -1,2-ethanedione monomer (0.6215 g) is dissolved in 1.3 ml of dioxane, and 0.621 .mu.g of alpha, .alpha.-azobisobutyronitrile is added. AIBN (0.1 wt%, based on monomer weight) and polymerized in an inert atmosphere at 55 ° C for 5 hours. The polymer was purified by triple precipitation from dioxane to methanol. 0.27 g of a light yellow polymer having a Mn > 156,000 was obtained in 43% yield.
