Ethylenediaminetetraacetic Acid → Styrene

Participants

Reaction Steps

0.015 part of paramenthane hydroperoxide and subsequently 0.04 part of sodium formaldehyde sulfoxylate were introduced into the system to initiate polymerization. Four hours later from the initiation of polymerization, 0.01 part of paramenthane hydroperoxide, 0.0015 part of ethylenediamine tetraacetic acid and 0.001 part of ferrous sulfate were introduced. Ten hours later from the initiation of polymerization, residual monomers were removed by deaeration under reduced pressure, and the polymerization was completed. Thus, rubber latex containing rubbery polymer particles obtained by copolymerizing 75% by weight of butadiene and 25% by weight of styrene was prepared.
