Partial to particular particles : The morphology of the polymer particles can be controlled in ethylene/CO copolymerization by pressurizing catalyst‐containing 1‐octanol droplets dispersed in water. The palladium catalyst should be harnessed with lipophilic long alkyl chains. Polymer particles of 0.5–1.0 mm size (see micrographs) with bulk densities of 0.2–0.3 g mL −1 are produced without reactor fouling.
