Abstract
Provided are transparent molded bodies for use as a scintillator for measuring the type and intensity of ionizing and non-ionizing radiation, including an organic polymer and, if desired, at least one additive which, under the influence of at least one of ionizing and non-ionizing radiation, emits scintillation radiation in the range from UV to IR light, the aim is to improve optical and mechanical properties, robustness against environmental influences and the manufacturability. This was achieved in that the organic polymer at least in part contains a polyaddition product of polyfunctional isocyanates and one or more polyfunctional hardener components.
Claims15
A transparent molded body for use as a plastic scintillator for measuring a type and an intensity of at least one of ionizing and non-ionizing radiation, comprising:
- an organic polymer,
- wherein the organic polymer, at least in part, contains a polyaddition product of polyfunctional isocyanates with one or more polyfunctional hardener components, wherein —NCO groups of the polyfunctional isocyanates are connected to aliphatic carbon atoms, wherein —OH groups or primary amino groups of the one or more polyfunctional hardener components are connected to aliphatic carbon atoms, wherein the organic polymer is a primary scintillator and emits scintillation radiation in a range from UV to IR light under the influence of ionizing and/or non-ionizing radiation;
- and
- wherein a) the polyfunctional isocyanates are diisocyanates comprising mononuclear or polynuclear aromatic and/or heteroaromatic groups, and/or b) the one or more polyfunctional hardener components comprise one or more aromatic rings, wherein the polyfunctional hardener components are selected from the group comprising bisphenol A ethoxylate, bis(hydroxyethyl) terephthalate and hydroquinone bis(2 hydroxyethyl) ether and mixtures thereof.
