(57)Abstract
The present invention relates to a process tor preparIng an a lesat partially crosslinked elastomer, characterized in that
the process comprises reacting by contacting; 1) an elastomeric polymer comprising ethylens/....- olefin interpolymer
containing reactive substituents, with 2) a crosslinking agent (a) containing two or more reactive substituents differing
from those contained in the elastomeric polymer, and b) having a number average molecular weight less than 2000,
each of the reactive substituents selected such that (i) those of the elastomeric polymer will react with those of the
crosslinking agent to at least partially crosslink the functionalized elasomeric polymer and (ii) each of the reactive
substituents is selected from carboxylic acid, carboxylic anhydride, carboxylic acid salt, hydroxy, epoxy and
isocyanate.
