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.

Abstract: The invention provides a stabilising composition for polymeric materials, comprising: a. a first derivatised phenolic antioxidant; b. at least one secondary arylamine having the formula (I): NHRyRx wherein: the or each R, which may be the same or different, independently denotes an optionally substituted hydrocarbyl group; x and y are each independently from 0 to 5 provided that at least one of x and y is at least 1; and provided that at least one R is an optionally substituted hydrocarbyl group having at least 9 carbon atoms; and c. one or more antioxidant boosters independently selected from: i. a second derivatised phenolic antioxidant having lower steric hindrance than the first derivatised phenolic antioxidant; ii. a hindered amine; iii.

Abstract: A method for forming, on a substrate, a seed layer enabling the subsequent deposition of a metal layer, including the step of immersing the substrate in a bath containing a material from the ethoxysilane or siloxane family and a copper or nickel amidinate.
