<p>A method for producing a filled water-crosslinkable silane copolymer composition comprising (A) a silane copolymer having a silane content of from 2 to 50 percent by weight, (B) a second polymer prepared from at least one olefin monomer selected from the group consisting of ethylene, propylene, butene, isobutylene, octene, 4-methyl-pentene-1 and hexene, (C) at least one filler in an amount of from 5 to 75 percent by weight of the total weight of the composition and (D) an organometallic silanol condensation catalyst, in which method the second polymer, filler and silanol condensation catalyst are blended together to form a masterbatch premix in which the silanol condensation catalyst is substantially homogeneously dispersed and subsequently blending the masterbatch premix with the silane copolymer to form a water-crosslinkable silane copolymer composition in which the silane content is from 0.5 to 25 percent by weight.</p> |
