DIFFUSION OF ORGANIC-MOLECULES THROUGH EPOXY ACRYLIC COPOLYMER FILMS/

The diffusion coefficients of limonene, myrcene, linalool and pine oil through films of a comb copolymer with advanced bisphenol A-epichloro hydrin epoxy as the backbone and poly(styrene-co-acrylic acid) grafts were determined by means of inverse gas chromatography. In the case of pine oil, the six isomers present in the supplied product were charac terised by distinct diffusion coefficients. Diffusion coefficients wer e found to increase in line with the molar volume of the organic molec ule: limonene < pine oil < linalool < myrcene.
