Abstract
The present disclosure relates to unsaturated polyolefins and processes for preparing the same. The present disclosure further relates to curable formulations comprising the unsaturated polyolefins that show improved crosslinking.
Claims12
A curable composition comprising (A) a polyolefin component and (B) a curing component comprising a cross-linking agent, wherein the (A) polyolefin component comprises an unsaturated polyolefin of the formula A1L1L2A2, wherein:
- L1 is a polyolefin;
- 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 hydrocarbylene group;
- and
- A2 is 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.
