Polarization variability is one of the most ubiquitous characteristic of blazars. Near infrared (NIR) polarization measurements of blazars are not common, contrary to the optical ones. Nonetheless, the NIR regime can be essential to understand correlated or non-correlated behaviour between the optical and radio energy ranges. In this work, we report on NIR polarimetry measurements of a sample of 28 blazars, collected with LIRIS at WHT/La Palma in several campaigns during 2011. The majority of the blazars were observed more than one epoch using two filters (J and Ks). Here we present preliminary results for few selected targets. [ABSTRACT FROM AUTHOR]
