The source of information was a big Database that comprises the P and D values for 20 March 2015 about 900 polymers. The method of the modified atomic contributions was revisited using much Accepted 22 March 2015 enlarged set of polymeric structures. In addition, a novel one, the bond contribution method, was Available online 4 April 2015 employed for the first time for predictions of the P and D values of a standard set of gases (He, H , O , N ,
