الإجراء التجريبي

34.7 parts by weight of behenyl acrylate, 3.22 parts by weight of acrylic acid (30 mol % of the total quantity of monomers) and 0.72 parts by weight of dodecanethiol are dissolved in 75 parts by weight of toluene, 0.75 parts by weight of the radical initiator azobisisobutyronitrile (AIBN) is added, and the resulting mixture is reacted for 16 hours at 70° C. under an atmosphere of nitrogen. Subsequently, the product is precipitated in 1 liter of methanol, and is then dried, thereby yielding an acrylic acid-behenyl acrylate copolymer (1). The weight average molecular weight, measured by GPC against polystyrene standards, is 14,800. The acid value is 61 mgKOH/g, and the melting point is 66° C.
