Nitrogen; N2; [7727-37-9]2.29-13.8
 Method/Apparatus/Procedure:
   The solubility has been measured by a volumetric method. Measurements were performed using an apparatus similar to that employed by Meares1.

 Source and Purity of Materials:
   Anionically polymerized PS sample having Mw = 106 000 was used.
He, Ar, Kr, Xe and N2 were obtained from Takachiho Kagaku Kogyo, Co. Ltd., and the purity of each gas exceeded 99.995 % by volume.
