Abstract: The invention concerns an antidegradant blend for polymers, comprising: a. an antioxidant selected from one or more of: i. a phenolic antioxidant; ii. an organic phosphite antioxidant; and: b. an inorganic antioxidant or reducing agent; wherein the composition is absent any metal carboxylate or buffering agent having the capacity to buffer in aqueous solution at a pH range from 4 to 8.

Abstract: The present invention relates to a precursor material for an insulation composition, comprising: a crosslinkable graft polymer comprising a polyolefin component and a polyene component; and an antioxidant. The present invention also relates to an insulation composition obtained from the precursor material.

Abstract: The present invention is directed to an antidegradant blend, comprising: at least one metal carboxylate; at least one inorganic phosphite; at least one phenolic antioxidant; and at least one organic phosphite antioxidant. As examples, the metal carboxylate may comprise a metal stearate, a metal lactate and/or a metal benzoate while the inorganic phosphite may comprise one or more metal hypophosphites.

Abstract: The invention concerns a stabilising composition, comprising: at least one antioxidant comprising one or more of: a phenolic antioxidant, a phosphite antioxidant, a sulphur-containing antioxidant, and an aminic antioxidant; and at least one buffering agent, wherein the buffering agent has the capacity to buffer in aqueous solution at a pH range from 4 to 8.

Abstract: The invention concerns an antidegradant blend, comprising: an aminic component comprising a hydroxylamine and/or a hydroxylamine precursor; and an inorganic antioxidant or reducing agent.
