Abstract

Composizioni poliestere ad elevata viscosità del fuso ottenute per reazione ad alta temperatura di una resina poliestere, previamente essiccata, con almeno un composto di formula generale (I): (FORMULA I) dove X rappresenta un radicale organico divalente tale da dare origine a eterocicli scelto fra quelli di formula -CR1R2-CR3R4- ovvero -CR1R2-CR3R4-CR5R6-, con R1, R2, R3, R4, R5 e R6, uguali o differenti tra loro, che rappresentano un atomo di idrogeno od un metile; R rappresenta un radicale polivalente alifatico (lineare, ramificato o ciclico) con un numero di atomi di carbonio compreso tra 1 e 30 o aromatico con un numero di atomo di carbonio compreso tra 6 e 30, eventualmente sostituito con eteroatomi; n e m sono numeri interi compresi tra 1 e 5.High viscosity polyester compositions of the melt obtained by reaction at high temperature of a polyester resin, previously dried, with at least one compound of general formula (I): (FORMULA I) where X represents a divalent organic radical such as to give rise to chosen heterocycles among those of formula -CR1R2-CR3R4- or -CR1R2-CR3R4-CR5R6-, with R1, R2, R3, R4, R5 and R6, equal or different from each other, which represent a hydrogen atom or a methyl; R represents an aliphatic polyvalent radical (linear, branched or cyclic) with a number of carbon atoms between 1 and 30 or aromatic with a number of carbon atom between 6 and 30, possibly replaced with heteroatoms; n and m are integers between 1 and 5.
