The polarization of SN 2002ic interacting with a dense circumstellar envelope is calculated in the context of the asymmetric version of a previously proposed spherical interaction model .
The circumstellar envelope is taken to be oblate .
The observed polarization ( 22 ) can be reproduced for an aspect ratio of 0.65-0.7 assuming inclination angles > 60 ^ { \circ } .
This model predicts a weak sensitivity of the line profiles to the orientation , in agreement with the absence of significant variations of the line profiles among SN 2002ic-like supernovae .
We propose a test for distinguishing between the binary and single star progenitor scenarios based upon the polarization distribution function for the growing sample of these events .
