Curable compositions comprising telechelic polyolefins

A curable formulation comprising (a) from 80 wt % to 99.99 wt % of a telechelic polyolefin, and (b) from 0.01 wt % to 20 wt % of a curing component comprising a crosslinking agent, wherein the telechelic polyolefin has the formula (I):

• A1L1L2A2 (I);
• L1 is an ethylene/alpha-olefin copolymer comprising units derived from greater than or equal to 50 wt % of ethylene and a C3 to C30 alpha-olefin;
• A1 is selected from the group consisting of a vinyl group, a vinylidene group of the formula CH2═C(Y1)—, a vinylene group of the formula Y1CH═CH—, a mixture of a vinyl group and a vinylene group of the formula Y1CH═CH—, a mixture of a vinyl group and a vinylidene group of the formula CH2═C(Y1)—, a mixture of a vinylidene group of the formula CH2═C(Y1)— and a vinylene group of the formula Y1CH═CH—, and a mixture of a vinyl group, a vinylidene group of the formula CH2═C(Y1)—, and a vinylene group of the formula Y1CH═CH—;
• Y1 at each occurrence independently is a C1 to C30 hydrocarbyl group;
• L2 is a C1 to C32 hydrocarbyl group;
• and
• A2 is a hydrocarbyl group selected from the group consisting of:
• wherein the endocyclic double bond in (AC) and (AF) may be between any two adjacent carbon atoms that are ring members, and wherein the pendant methyl group of (AF) may be connected to any carbon atom that is a ring member.
