ABSTRACT

• The aging of polymer systems involves
  different factors natural (light, heat,
  humidity), structural and accidental (impurities,
  oxidation processes occurred during processing),
  all these being capable to significantly reduce
  the life-time of materials. The mechanisms of
  polymers degradation are highly complex.
• Thus, there can be initiated
  photo-cross-linking or photo-oxidative reactions
  of polymers accompanied by decrease in average
  degree polymerization, increase of polydispersity
  and formation of chemical structures capable to
  modify the properties of polymers.
• The present project envisages increasing
  knowledge in the investigation upon effect of
  external factors on stability of multi-component
  polymer systems. It is aimed to create a research
  team comprising 4 experienced researchers and 3
  doctoral students focused to acquire experimental
  data and to elaborate original theories in order
  to explain the performance loss of polymer
  systems during exposure to controlled
  environmental factors, and to evaluate their
  life-time prediction.
• It is considered that valuable scientific
  results will be provided, being comparable with
  those already existing at global level, and will
  contribute to increasing international visibility
  of Romanian research activity. The envisaged
  results will contribute to the finalization of
  doctoral theses to be realized by the young
  doctoral students included in the research team.

OBJECTIVES

• The present research project is focused on the
  transformations of polymers with different
  structures under weathering conditions and
  especially solar light.
• The following objectives were taken into
  consideration
• Immobilisation of dyes of different structures
  and concentrations onto natural and/or synthetic
  polymers
• Obtainment of multi-component systems containing
  polysaccharides
• Obtainment of semi-interpenetrating networks
  based on collagen or polyaspartic acid.
• Study of the influence of controlled
  environmental factors upon polymer systems
  colored with dyes (solar light, heat, humidity)
• Study of the stability of the multi-component
  systems to weathering conditions

5
Research directions

• The mentioned objectives are oriented in the
  following directions
• Obtainment of knowledge on the implications of
  some reactive dyes immobilized onto polymers and
  the determination of the biological effects in
  correlation with their physico-chemical
  properties.
• Characterisation and evaluation of the stability
  of the multi-component systems containing
  polysaccharides at weathering conditions.
• Study of the photochemical behaviour of the
  natural polymers exposed to UV irradiation.
