So, over a longer time, the polymer chains can flow past each other.
This charge is enough to attract the second polymer chain.
Higher degree of cross-linking between the polymer chains has such effect too.
The number of growing polymer chains is determined by the initiator.
Last year, actually when I completed the research on synthetic polymer chains.
The atom is usually hydrogen, and this results in two polymer chains.
Similar, more recent advances have also come out of the polymer chains.
In general, the higher degree of branching, the more compact a polymer chain is.
Then, the number of defects in the polymer chain increases considerably.
These reactive products may also cause further degradation of the polymer chain.
