Abstract
Linear alternating polymers of carbon monoxide, non-conjugated alkenylbenzene compound and optionally ethylene are produced by contacting the monomeric reactants under polymerization conditions in the presence of an inert reaction diluent and a catalytic quantity of a catalyst composition formed from a compound of palladium, the anion of a strong non-hydrohalogenic acid having a pKa less than 2 and a bis(dialkylphosphino)alkane. The polymer products are thermoplastics and have utility as engineering thermoplastics.
