摘要：Disclosed is a method for viscosity breaking of a polypropylene polymer, apolypropylene copolymer or a polypropylene polymer blend, which process comprisesadding a chain transfer agent and an initiator to a polypropylene polymer, polypropylenecopolymer or polypropylene polymer blend and heating the resultant composition. Thechain transfer agent has a Cs value of greater than or equal to about 0.04 as measured inethylene polymerization at 130° C. The initiator is for example an organic or inorganicperoxide, a carbon based radical generator, a bis azo compound, a stable nitroxylcompound, a sterically hindered NO-acyl compound or a sterically hindered alkoxyaminecompound.
