dc.description.abstractThe grafting of triethoxyvinylsilane (TEVS) onto very low density polyethylene (VLDPE) via reactive extrusion was investigated with an emphasis on the temperature and amount of initiator used for the reaction. Two different peroxides (Luperox 101 and Peroxan PK 295P) were used as single initiators for the grafting reaction with and without an additional thermal stabilizer. Infrared spectra of the resulting polymers showed that grafting efficiency was high over the analysed temperature range from 120°C to 210°C. A new and more sensitive method, based on head space gas chromatography with mass spectrometry (head space GC–MS), was used to determine optimal grafting efficiencies. Above 160°C, the grafting efficiency for both initiators was greater than 80%. In general, grafting with the more reactive peroxide (P295) yielded more highly functionalized polymers. Optimization of the grafting process reduces the amount of unreacted grafting material, minimizing levels of free volatile components and reducing energy consumption. Melt viscosities were also analysed to identify unwanted side reactions. In general, compared to polymers produced with P295, those made with Luperox 101 exhibited more rapidly increasing complex viscosity with increasing amounts of initiator. T-peel adhesion tests were used to demonstrate the use of silane-grafted VLDPE as an adhesive on metal substrates. The T-peel strengths of modified VLDPE samples were between 0.6 and 2.6 N/mm, depending on the process conditions and the choice of initiator. The T-peel strength of Peroxan PK 295P was less dependent on initiator content, resulting in a more robust system for use in reactive extrusion technologies.de_CH
