Patents Assigned to SYNTHOS DWORY 7 SPOLKA Z OGRANICZONA ODPOWIEDZIALNOSCIA SPOLKA JAWNA
  • Polar additive for the synthesis of copolymers of vinylaromatic monomer and conjugated diene monomer having high vinylaromatic and low vinyl contents
    Patent number: 11525049
    Abstract: The present invention relates to the use of N,N?,N?-substituted hexahydro-1,3,5-triazine in the anionic polymerization of conjugated diene monomer and vinylaromatic monomer. Use of this polar additive produces copolymers having both high vinylaromatic and low vinyl contents, while the blockiness of the vinylaromatic unit can be tailored.
