Are there continuous polypropylene production plants that manufacture the final product without granulation?

I heard that after modification with a catalyst, the homopolymer products of continuous-process polypropylene can be sold directly without being granulated. Is that true?
There is no standard for what can be sold; polypropylene produced by continuous processes does not contain any additives.
So what’s the difference from products with a small intermittent unit?
Today, polypropylene technology can achieve the \"four no’s\" – namely, no granulation and no depolymerization. You can download the book \"Principles, Processes, and Technologies of Polypropylene\" from the website; it’s a great book.
The current issue with powder production in continuous polypropylene production methods is mainly due to the fact that while the polymerization capacity has been increased, the extrusion and granulation capacity has not kept up. The price is similar to that of the powder for small bodies.
Haven’t seen it; you can’t get a good price if it’s not in granular form
The new generation of catalysts no longer requires granulation.
