Forum:Polymerization - Cost to Activate?

hey there I've been playing my friend and something came up which I'm not sure about. I activated polymerization to try and fusion summon, and my friend chained magic jammer to stop me.

the question is...

do the monsters required for the fusion get sent to the grave as a cost to activate polymerization? or would I keep them in my hand.

thanks!
