Title (EN) CYCLOALIPHATIC POLYPHOSPHITES
(FR) POLYPHOSPHITES CYCLOALIPHATIQUES
Abstract:
(EN) A polymeric polyphosphite and copolymeric polyphosphite is described which contains a cycloaliphatic moiety, preferably cyclohexane dimethanol, in the polyphosphite backbone chain. Incorporation of the polymeric polyphosphite into synthetic polymers reduces the yellowness index of any polymer into which the polymeric polyphosphite additive has been added, as well as increased hydrolytic stability as well as increased resistance to migration in food packaging.
(FR) La présente invention concerne un polyphosphite polymère et un polyphosphite copolymère contenant un fragment cycloaliphatique, de préférence un cyclohexane diméthanol, dans la chaîne principale du polyphosphite. L'incorporation du polyphosphite polymère dans des polymères de synthèse réduit l'indice de jaunissement des polymères dans lesquels l'additif de type polyphosphite polymère a été ajouté, et permet également d'augmenter la stabilité hydrolytique ainsi que la résistance à la migration dans les emballages alimentaires.
