Claims
- 1. A process for the preparation of the addition product of a linear telechelic difunctional unsaturated polymer containing terminal functional reactive groups other than vinyl groups, comprising simultaneously reacting (a) 1,5-cyclooctadiene, (b) a difunctional ester of 2-butene-1,4-diol, wherein the functional groups are selected from the group consisting of hydroxyl, ester, alcohol, amine, acid, acyl halide, ketone, aldehyde, borane, amide, acid anhydride, ether, imide, halogen atom, alkyl, aryl and substituted aryl groups of up to about 30 carbon atoms, and mixtures thereof, and (c) H.sub.2, in the presence of at least one olefin metathesis catalyst to prepare an addition product of a linear difunctional unsaturated polymer, wherein H.sub.2 adds to a carbon--carbon double bond under ROMP reaction conditions.
- 2. The process of claim 1 wherein said esters of 2-butene-1,4-diol are selected from the group consisting of monoacetate, diacetate, monopropionate, dipropionate, monobutyrate, dibutyrate, monobenzoate, dibenzoate, monopivalate, and dipivalate.
- 3. The process of claim 1 wherein said olefin metathesis catalyst is a ruthenium-based catalyst system comprising a ruthenium compound (A), a phosphorus compound (B), and a compound (C) containing a carbon-to-carbon triple bond, wherein mole ratios of A:B:C expressed as compounds are in the range of about 1.0:0.01-100:0.01-100,
- said ruthenium compound (A) is a Ru(II), Ru(III), or Ru(IV) compound containing an anionic ligand (X) and optionally containing an arene ligand and optionally a phosphorus compound ligand;
- provided that said phosphorus compound (B) is optional if said ruthenium compound (A) contains a phosphorus-containing ligand.
- 4. The process of claim 3 wherein said compound (A) is (RuCl.sub.2 (.rho.-cymene)).sub.2, wherein said compound (B) is tricyclohexylphosphine, and wherein said compound (C) is 2-butyne-1,4-diol diacetate.
- 5. The process of claim 1 wherein said process is conducted at a temperature of from about -20.degree. C. to about 250.degree. C. and is conducted at a pressure of from about 0.1 to about 1000 atmospheres.
