In order to distinguish essays and pre-prints from academic theses, we have a separate category. These are often much longer text based documents than a paper.
The solubility of polymers in caprolactam and laurolactam at 150°C was studied, results being discussed in terms of polymer solubility parameters, hydrogen bonding and polymer crystallisation. Polymers soluble up to 10% by weight were dissolved in the monomers which were then polymensed by an anionic mechanism. Poly sulphone and polycarbonate acted as cocatalysts in polymensation of caprolactam, copolymers being formed. For all the other polymers polymensation of the monomers resulted in polymer blends....
