    摘要: Chlorinated and chlorosulfonated polyethylenes are produced by chlorinating substantially linear olefin polymers having a melt flow ratio, I.sub.10 /I.sub.2, .gtoreq.5.63, a molecular weight distribution, M.sub.w /M.sub.n, defined by the equation: M.sub.w /M.sub.n .ltoreq.(I.sub.10 /I.sub.2)-4.63, a critical shear rate at onset of gross melt fracture of at least 50 percent greater than the critical shear rate at the onset of surface melt fracture of a linear olefin polymer having about the same I.sub.2 and M.sub.w /M.sub.n and at least about 0.01 long chain branches/1000 carbons and a molecular weight distribution from about 1.5 to about 2.5 and their method of manufacture are disclosed. The chlorosulfonated polyethylenes are produced by treating the chlorinated polyethylenes with a mixture of gaseous chlorine and sulfur dioxide.
