Description

I will show that current mm-to-X-ray polarization trends observed during recent IXPE campaigns for high-synchrotron peaked blazars and the ROBOPOL trend for Fermi blazars, which relate the fractional polarization to the peak frequency of the synchrotron emission, can be successfully reproduced by a multi-zone scenario without the need for an energy-stratified scenario. I will also discuss some implications for the statistical properties of the polarization angle and the underlying acceleration processes.
