Abstract (en)
[origin: WO2014205191A1] 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.
