"Static and Dynamic Properties of Polymeric Systems with Strongly Interactive Groups"

9/01/1994 - 8/31/1997

Sponsor - NSF

The goal of the Project is to study the static and dynamic properties of heteropolymers with strongly interacting groups (SIG) including block copolymers in selective solvents, ionomers and associating polymers. In paricular we will study:

  • the configuration of copolymers with SIG of different architecture in selective solvents
  • the formation of micells and clusters
  • the phase diagram of the solutions of polymers with SIG
  • the dynamics of a single chain and of the clusters of chains
  • linear and nonlinear stress relaxation of polymeric systems with SIG

    Despite their chemical difference, these systems self-organize in a similar way and can be studied on the basis of the same models, utilizing common theoretical methods, such as those developed for the theory of block copolymers in the strong segregation regime.
