In PVC, intermediate order produces  a unique thermoreversible gelation property that makes PVC easier to  process than its crystalline  counterpart.

Current computational capability  does not allow us to evolve molecule  dynamics simultions to reach the  desirable state, i.e. intermediate  order, where we can analyze the  system properties.



We have developed a model  reduction approach to reduce the  simulation burden.



Local feature analysis and time  series methods are combined to  speed up the simulation while  retaining key features and dynamics.
