Abstract
The invention provides a method of preparing a crosslinked polymer, which method comprises polymerising branched polyunsaturated monomers by a metathesis polymerisation reaction, wherein the branched polyunsaturated monomers contain acyclic ethylenically unsaturated groups that are capable of undergoing polymerization by a metathesis reaction such that the metathesis polymerisation produces a crosslinked polymer and substantially no non-volatile ethylenically unsaturated by-products.
Claims10
1-21. (canceled)
A coating or adhesive product comprising:
- (1) branched polyunsaturated monomers that:
- (a) comprise at least a general structural unit (I):
- BR1R2R3 (1)
- where B represents an atom or core, and where each moiety R1, R2 and R3, which may be the same or different, contains at least one acyclic ethylenically unsaturated group which (i) is located within 6 atoms from the end of the moiety, and (ii) is capable of undergoing polymerization by a metathesis reaction contain terminal or near terminal acyclic ethylenically unsaturated groups that are capable of undergoing polymerisation by a metathesis reaction to form a crosslinked polymer to afford a crosslinked polymer and substantially no non-volatile ethylenically unsaturated by-products, and
- (b) are, or are derived from, a natural oil, and
- (2) an olefin metathesis catalyst.
A method of preparing near terminal ethylenically unsaturated carbonyl compounds, which method comprises subjecting a carbonyl compound comprising an acyclic ethylenically unsaturated group to a cross-metathesis reaction with substantially pure 2-butene.
