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.
