Production of the polyolefine graft copolymer which possesses the low molecular weight side chain which uses polymerization characteristic peroxide as the initiator

摘要

(1) under oxygen non- existing the process which emits the propylene polymer material; The process which manufactures the propylene oxide polymer material which includes all peroxide where (2) it adds to the propylene polymer material which emits the oxygen of the quantity which adjusted, 0.004 volume % to be more 15 volume % discloses the said polymer to the oxygen of a less quantity at temperature of the 40C - the 140C, per kilogram of Pol pyrene polymer material is more than 1mmol; (3) optionally, the propylene oxide polymer material substantially at least it is temperature of the 80C in non oxidation atmosphere, but the process which is heated at the temperature which is lower than the softening point of the said polymer; (4) in non oxidation atmosphere, processing the propylene oxide polymer material, at least with the graft monomer of 1 where it can be polymerized by freely radical kinds, at least under existing of the additive of 1 kinds, (a) at least the hydroxylamine derivative polymerization inhibiter of 1 kinds, and, (b) at least the thio, nitro of 1 kinds, it is selected from halogen substitution aliphatic series and the aromatic compound, or aliphatic series and the aromatic phosphine derivative the process which adjusts the molecular weight of the side chain of the graft monomer which was polymerized; And (5) remaining non it activates free radical in the graft conversion propylene polymer material which is obtained manufacture the graft copolymer which possesses the low molecular weight side chain and with the process which removes unreacted vinyl monomer from the said material.
