On the crystalline-amorphous supermolecular structure of poly(4-methyl-1-pentene) films cast from solution: experimental evidences and theoretical remarks.

We regard the formation of crystalline-amorphous structure of polymeric fil ms cast from solution. We pay a special attention to its formation on a lev el of single quasicrystalline domain, and try to embark on the problem, whe n a possibly large group of such domains has to be considered. In the forme r, one is nearly enforced to make use of a modification of the stochastic d iffusion-limited aggregation model, first introduced by Witten and Sander. In the latter, certain diffusion-type (Potts-like) models, invented for pol ycrystalline microstructure formation, could be adopted. When considering t he problem on the first level mentioned, one may notice an apparent agreeme nt between experiment and theory, whereas on the second level, some concept ual similarity seems to be attractive.
