Hydroxyl-terminated PDMS as a cure-control additive for the silane crosslinking of polyolefins

摘要

The scorch of the silane-functionalized polyolefin has (1) a number average molecular weight (Mn) of at least 4,000 grams per mole (g / mol) (≥), (2) a viscosity of at least 90 centipoises (cP) And (3) polydimethylsiloxane (PDMS) having a hydroxyl group content of less than or equal to 0.9 weight percent (wt%) based on the weight of the PDMS.
