SIP is Surface Initiated Polymerization.
The SIR effect or steric inhibition of resonance is also known as ortho effect.
It is the effect specially noticed in ortho substituted aniline. When there is a steric hindrance between group at ortho position and -NH2 group, the -NH2 group rotates and it inhibits Resonance since it is not in the same plane anymore..
This makes the compound more basic as the electron on the -NH2 group is now available for donation..
Hope it helps.. :)
