摘要:
A two-step process involving bulk polymerization of a mixture of hydrophobic and hydrophilic monomers followed by emulsion polymerization conveniently yields a stable copolymer latex composition having improved properties. The process is particularly useful for preparing carboxylated styrene-butadiene latex compositions.
