A process for the preparation of an addition product of a linear telechelic difunctional unsaturated polymer containing terminal functional reactive groups other than vinyl groups, involves simultaneously reacting at least one cyclic olefin of from about 4 to 30 carbon atoms, at least one difunctional acyclic olefin of up to about 30 carbon atoms, and at least one reactant YZ in the presence of at least one olefin metathesis catalyst to prepare an addition product of a linear difunctional unsaturated polymer, wherein YZ is capable of adding to a carbon--carbon double bond under ROMP reaction conditions.

Catalyst activity life of an iron oxide-containing catalyst is extended by contacting such catalyst with a feedstream containing about 0.0001 to about 0.01 mole of oxygen per mole of feed in the substantial absence of an oxidation catalyst.

Yeast autolysis is enhanced by the addition of certain exogenous enzymes to the yeast slurry at concentrations of from about 0.01-1.0 weight percent, said enzymes being selected from the group consisting of papain, ficin, bromelain, pancreatin, and aspergillus protease.
