Abstract

A polymeric phenolic antioxidant is disclosed. In particular, the polymeric phenolic antioxidant is the reaction product of a hydroxybenzene, a diene, and an aldehyde. The present disclosure is also directed to a stabilizer composition, a polymeric composition, and an article comprising the polymeric phenolic antioxidant. The present disclosure is also directed to a method of making the polymeric phenolic antioxidant wherein the method comprises: reacting a hydroxybenzene and a diene to obtain a first reaction product; reacting the first reaction product in the presence of the hydroxybenzene and an aldehyde to obtain a crude reaction product comprising the polymeric phenolic antioxidant.

Abstract

The invention provides a hydrolytically stabilised phosphite composition, comprising: a. a phosphite antioxidant which is a liquid at ambient conditions and comprises a blend of at least two different phosphites of Formula I: wherein R1, R2 and R3 are independently selected alkylated aryl groups of Formula II: wherein R4, R5 and R6 are independently selected from the group consisting of hydrogen and C1 to C6 alkyl, provided that at least one of R4, R5 and R6 in each phosphite is selected from the group consisting of tert-butyl and/or tert-pentyl; and b. a nitrogen-containing compound comprising a nitrogen atom, wherein the nitrogen atom: i. has a pKaH value of from about 7 to about 11; and ii. is sp3 hybridised, and wherein the nitrogen-containing compound is absent any labile protons.

Abstract

The invention provides a stabilising composition for a polyol and/or a polyurethane, comprising: a) a first derivatised phenolic antioxidant having a molecular weight of at least about 400 g/mol and a melting point of less than about 100°C; b) a second derivatised phenolic antioxidant having lower steric hindrance than the first derivatised phenolic antioxidant, which is a solid at ambient conditions; and c) a secondary antioxidant comprising a phosphite and/or a thioester, and also disclosed is a fire retardant blend comprising the stabilising composition and a fire retardant.
