✦ Synopsis

AbstraetmThe paper is concerned with the behaviour of polyethylene terephthalate in the process of vibratory milling. This polymer belongs to the class of heterochain macromolecular compounds; depending on the mechanical and other working conditions (medium, temperature, etc.), it may exhibit various chemical reactions. In inert media (gaseous or liquid) and in the absence of humidity, mechanochemical destruction is radically initiated. The presence of small quantities of water favours hydrolysis, activated mechano-chemically.

The functional end groups (carboxylic and hydroxylic) in the polyester chain permit the initiation, for the first time in the field of meehano-chemistry of macromolecular compounds, of the processes of polycondensation by using diamines in the reaction.

Low and high density polyethylenes were irradiated in a cobalt-60 source in air at a low dose rate. Differences in behaviour in grafting were observed. The form of the kinetic curves, the temperature effect and the effect of the foil thickness suggest that there are different grafting mechanisms dep
