Hi! evveryone I am reading a article about metallocene catalyzed polymerization. There is a below writings :
" In a semibatch slurry reactor,the concentration of macromonomers increases with time,while the concen-tration of ethene may decrease due to mass transfer limitations. Diffusion limitations also broaden the molecular weight distribution in copolymerizations."
I would like to know the meanings of mass transfer limitations and diffusion limitations.
Would you inform me about that? I majored the chemistry, so I am not familiar with a term about polymer.
Thank you
