  1. LIGNIN MODIFIED POROUS BPA.DA-St POLYMERS CHARACTERISED BY THERMAL ANALYSIS B. Gawdzika, M. Sobiesiaka, B. Podkościelnaa, O. Sevastyanovab a Department of Polymer Chemistry, Faculty of Chemistry, Maria Curie-Sklodowska University, pl. M. Curie-Skłodowskiej 5, 20-031 Lublin, Poland bKTH, Royal Institute of Technology, Department of Fibre and Polymer Technology, SE-10044 Stockholm, Sweden COST ACTION FP1105 COIMBRA 8TH MAY 2014

  2. Scheme of the polymer synthesis Conditions of synthesis: - suspension-emulsion process carried out at 80ºC for 18 h. - AIBN(the initiator) - toluene and decanol (pore-forming diluents) COST ACTION FP1105 COIMBRA 8TH MAY 2014

  3. Thermal analysis Operational conditions of therogravimeric measurements: heating rate 10ºC/min dynamic atmosphere of helium 40mL/min range of temperature 50-800ºC mass of the sample ca. 10mg COST ACTION FP1105 COIMBRA 8TH MAY 2014

  4. TG (left) and DTG (right) plots of the polymers. COST ACTION FP1105 COIMBRA 8TH MAY 2014

  5. Conclusions: • Thermal decomposition process for all the studied materials proceeds in almost the same range of temperatures 325-535ºC. • Introduction of L, LA or LEA to the polymeric structure resulted in the decrease of the decomposition rates. • The lignin component (especially L and LA) slow down thermal destruction of the BPA.DA-St. • The presented polymers containing lignin additives can be considered as potential precursors for carbonisation processes.
