Macromolecules containing fibrous inorganic and organic fillers in polyolefins like polypropylene and in other semi-crystalline plastic polymers molded under stress or orientated (stress induced) will form trans. crystals epitaxially on the fiber surface in-situ in the polymer matrix. However, without fiber fillers in these same matrix no trans. crystals are formed. If transcrystallinity could be induced in unfilled semi-crystalline molded plastics what would be the outcomes observed  in the molded part. What physical chemical changes versus a control molded sample of the same material not be trans. induced?  Has the field of polymer science and physical been able to model or predict what factors induce either alpha transcrystallinity or beta transcrystallinity?
