Beschreibung
Zusammenfassung:	A neutron shielding polymer composition comprising a polymerization product of a base monomer ingredient containing as an essential ingredient at least one monomer selected from the group consisting of alkyl methacrylates containing 1-4 carbon atoms in the alkyl group and styrene in admixture with a saturated boric acid ester which contains as an essential constituent component a polyol containing 3-16 carbon atoms and in which a molar ratio A of said polyol to boron atoms in said boric acid ester formed from said polyol being in the range of 0.6
