Sorption, Diffusivity and Swelling Measurements of a-Olefins in Polyolefins by Using a New Experimental Setup:

The experimental set-up consists of a high-pressure, high-temperature feeding tang, where the desired monomer temperature is obtained, the suspension micro-balance (SMB), where sorption measurements are carried out and a high-pressure, high-temperature view cell (VC), where elongation measurements are conducted. The view cell is connected to a stereomicroscope, equipped with a high-resolution camera for continuous frame grabbing. Sample photos with respect to time are analysed using the Image Analysis-Pro software. Sample length and width are measured versus time, whereas sample thickness is measured during the measurement. The new experimental set-up is capable of working at high temperatures (up to 120oC) and high pressures (up to 300 bar), obtaining simultaneously sorption and swelling curves under isobaric and isothermal conditions.
