Abstract:
A method for effectively inhibiting polymerization of an easily polymerizable compound comprising the steps of:a) feeding an easily polymerizable compound to an apparatus, wherein the apparatus includes a sidewall and an inside; b) providing a tubular member on the sidewall of the apparatus, wherein the tubular member opens to the inside of the apparatus; c) setting the tubular member to have a downward gradient (&agr;) toward the inside of the apparatus, flowing condensate downwardly in the tubular member, and preventing condensate from residing in the tubular member such that polymerization of the easily polymerizable compound is effectively inhibited; and d) wherein the step of setting the tubular member comprises the step of fixing the gradient (&agr;) in a range of 3Â° to 70Â° relative to the horizontal.
