The microfibril diameter proved to be correlated with the initial morphogenesis. This structural feature is directly issued from the fragmentation of the crystal lamellae. We have demonstrated a memory effect of the chain topology on the fibril microstructure. The amorphous [price](PDF) Scientific Opinion on the safety of polyvinyl [hdpe]The polymer consists of approximately 75 % w/w PVA units and 25 % w /w PEG units.
