The invention provides a process for grafting silane or silicone functionality onto a polyolefin, comprising reacting the polyolefin with an unsaturated monomer (A) containing an olefinic &#x2014;C&#x2550;C&#x2014; bond or acetylenic &#x2014;C&#x2261;C&#x2014; bond and a reactive functional group X in the presence of means capable of generating free radical sites in the polyolefin and with an organosilicon compound (B) having a functional group Y which is reactive with the functional group X of the unsaturated monomer (A), characterized in that the unsaturated monomer (A) contains an aromatic ring or a further olefinic double bond or acetylenic unsaturation, the aromatic ring or the further olefinic double bond or acetylenic unsaturation being conjugated with the olefinic &#x2014;C&#x2550;C&#x2014; or acetylenic &#x2014;C&#x2261;C&#x2014; unsaturation of the unsaturated monomer (A).

Modified polyolefins

Branched silicone (organopolysiloxane) resins and preparation method and use thereof are provided, which contain at least one group selected from phosphonate and phosphinate groups and at least one organic group containing nitrogen. Such silicone resins can be used in thermoplastic, thermosetting or rubber organic polymer compositions to reduce the flammability of the organic polymer compositions.
