Abstract:
The present invention discloses a poly((meth)acrylic acid-b-styrene-b-butadiene-b-styrene) block copolymer latex and a method for preparing the same. The poly((meth)acrylic acid-b-styrene-b-butadiene-b-styrene) block copolymer latex is directly and stably obtained by emulsion polymerization in the presence of an amphiphilic macromolecule reversible addition fragmentation chain transfer agent as both chain transfer agent and reactive emulsifier. The present invention has simple operation, and the process is environmentally friendly and energy-saving, the product poly ((meth) acrylic acid-b-styrene-b-butadiene-b-styrene) block copolymer latex has a good prospect in many fields, such as bitumen modification, adhesives, polymer toughening and the like.
