Abstract
The results of the DSC investigations show that the phase composition of cetyl alcohol (CA) in the highly dispersed state in micropores of HDPE and PTFE polymer matrices differs markedly from that in the free state. Crystallization of CA from melts and solutions in the free state results in the formation of different low temperature modifications (the β- or γ-form), whereas crystallization in the studied polymer matrices under like conditions invariably takes place and results in a blend of the high-temperature α-form plus one of the two possible low-temperature β-forms. The ratio of the forms changes as filling of the micropores decreases (as the degree of dispersity of CA particles increases) in the direction of a higher content of the α-form.
