Abstract
Solid catalyst particles, especially Ziegler catalysts, are made into a form and shape that is easier to handle, without changing their surface area or adversely affecting their activity by "matting" the catalyst particles with a fibrillatable PTFE by mechanical shearing action and subsequently shaping the "mat", followed by controlled sizing and shaping into the form of pellets, tablets, and the like by known mechanical means.
