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.

A composition comprising the reaction product of a polypropylene comprising at least 50 mol % propylene, and having a molecular weight distribution (Mw/Mn) greater than 6, a branching index (g′.sub.vis) of at least 0.97, and a melt strength greater than 10 cN determined using an extensional rheometer at 190° C.; and within the range from 0.01 to 3 wt % of at least one organic peroxide, by weight of the polypropylene and organic peroxide. Such hyperbranched polypropylenes are useful in films, foamed articles, and thermoformed articles.

A process is described for preparing a storage-stable mixture including an MDT silicone resin containing hydroxyl groups and an organic compound that contains at least one epoxy group.
