Abstract
Abstract The invention relates to a method of preparing polyether-ester-amide block copolymers having recurrent units of the general formula: ##STR1## wherein A is a polyamide sequence and B a linear or branched polyoxyalkylene glycol sequence, the alkylene radical of which comprises at least two carbon atoms, and wherein n indicates that there is a great number of recurrent units. The plastic materials prepared by the novel method have mechanical properties which allow them to be used in technological transformation operations for the manufacture or moulded or extruded articles such as films, sheaths, fibres for textiles products, etc.. They may also be used for making bonded or welded linings. The novel method comprises reacting in the fused state at an elevated temperature and under high vacuum a dicarboxylic polyamide, the COOH groups of which are located at the chain ends, with a polyoxyalkylene glycol hydroxylated at the chain ends, in the presence of a catalyst constituted by a tetraalkylorthotitanate having the general formula Ti(OR) 4 , wherein R is a linear or branched aliphatic hydrocarbon radical having 1 to 24 carbon atoms, such a methyl, isopropyl, butyl, ethylhexyl, dodecyl, hexadodecyl.
