10 Claims

1. A moisture-curable polyolefin formulation comprising:

(A) a (hydrolyzable silyl group)-functional polyolefin prepolymer; and

(B) a condensation-cure catalyst system comprising a compound that is an iron(II) acetylacetonate or an iron(III) acetylacetonate, wherein each acetylacetonate is unsubstituted or independently substituted with from 1 to 5 alkyl groups, wherein each alkyl group is unsubstituted (collectively called “iron (alkyl)acetylacetonate”);

wherein the amount of (A) is from 79.0 to 99.99 weight percent (wt %) and the amount of (B) is from 21.0 to 0.01 wt %, respectively, of the moisture-curable polyolefin formulation; and

wherein the (A) (hydrolyzable silyl group)-functional polyolefin prepolymer is a copolymer of copolymerized ethylene and an alkenyl-functional hydrolyzable silane with the alkenyl-functional hydrolyzable silane positioned along a backbone of the prepolymer.
