Ascorbate short-stops |
摘要 |
The polymerization of butadiene and styrene in an emulsion, free-radical polymerization process using a persulphate initiator is effectively short-stopped by the addition of ascorbic acid or the sodium or potassium salts thereof. The butadiene-styrene polymer so produced may be used in those end uses generally associated with the prior known use of such polymers.
