Abstract: A process for synthesizing a product of formula Br—(CH2)n—R by hydrobromination, by reacting: a reagent of formula (I) R1-CH?CH—R2 in which R1 and R2, identical or different, are chosen from H or an alkyl radical comprising 1 to 30 carbon atoms, which is saturated or unsaturated, linear or branched, functionalized or non-functionalized, with a molar excess of HBr relative to the reagent of formula (I), in the presence of a radical initiator, and optionally in the presence of at least one solvent, said process including a step A of mixing at least reagent I and the HBr, each of the latter arriving in the form of a flow of liquid into a mixing device dA.

Abstract: The invention concerns a crosslinkable composition of functionalized polyolefin powder comprising a functionalized polyolefin (A) having an MFI of at least 20 (190° C. 2.16 kg), a product (B) having a function for crosslinking (A), the composition having a grain size distribution between 100 and 400 &mgr;m. Said composition is useful for slush moulding, for thermoforming sheets or injection on an insert.
