Elastomeric sol/gel blends |
摘要 |
The processability of an uncured soft elastomer is improved by blending the elastomer under shear conditions with a terpolymer of ethylene with carbon monoxide and with a copolymerizable ethylenically unsaturated monomer in the presence of a crosslinking agent for polymer (T) which does not substantially cure elastomer (E). Gel resulting from crosslinking polymer (T) improves the properties of the blend as compared with the soft elastomer alone. When elastomer (E) and the crosslinking agent for polymer (T) risk undergoing a reaction which would result in substantially crosslinking elastomer (E), one may substitute another soft elastomer (E1) for elastomer (E) to avoid this undesirable result and then blend the resulting composition with elastomer (E).
