Abstract
A plastic scintillator which comprises using as the matrix resin thereof a copolymer obtained by polymerizing (a) at least one compound represented by the general formula I: ##STR1## wherein, X and Y independently denote hydrogen atom or methyl group, providing that they do not exclusively denote methyl group, or a monomer mixture containing at least one compound of the general formula I in a weight proportion of at least 0.4 to the polymerizable monomer mixture to be used in the presence of (b) at least one monomer having at least two carbon-carbon double bonds capable of radical polymerization in the molecular unit thereof.
Claims19
A plastic scintillator in which a scintillating substance is incorporated in a matrix resin comprising a copolymer obtained by polymerizing a polymerizable mixture comprising at least 40 percent by weight of (a) at least one compound represented by the general formula I:
- ##STR6## wherein, X and Y independently denote hydrogen atom or methyl group providing they do not exclusively denote methyl group, and a crosslinking amount of (b) at least one copolymerizable monomer possessed of two carbon-carbon double bonds capable of radical polymerization in the molecular unit thereof selected from the group consisting of compounds represented by the general formula II:
- ##STR7## wherein, R denotes hydrogen atom or methyl group and n an integer of the value of 3 to 8;
- compounds represented by the general formula III:
- ##STR8## wherein, R and R' independently denote hydrogen atom or methyl group and m an intrger of the value of 1 to 23;
- and compounds represented by the general formula IV:
- ##STR9## wherein, R denotes hydrogen atom or methyl group.
