POLYETHER-BASED BLOCK COPOLYMERS HAVING HYDROPHOBIC DOMAINS
The invention relates to a polymerization method in which alkyl glycidyl ethers and epoxides, such as ethylene oxide, polypropylene oxide, 1-ethoxyethyl glycidyl ether and gycidol, are copolymerized and block copolymers are synthesized. The inventive methods include an initiator, oligomer blocks of...

Zusammenfassung: | The invention relates to a polymerization method in which alkyl glycidyl ethers and epoxides, such as ethylene oxide, polypropylene oxide, 1-ethoxyethyl glycidyl ether and gycidol, are copolymerized and block copolymers are synthesized. The inventive methods include an initiator, oligomer blocks of 1 to 40 alkyl glycidyl ether units of type (I), (II) or (III), and 80 to 1000 epoxy units of large polyether blocks, such as polyethylene oxide (PEO), polypropylene oxide (PPO), polyethoxyethylene glycidyl ether (PEEGE), linear and branched polyglycidol (PG, hbPG) or random copolymers of two, three or four different epoxide units, such as ethylene oxide (EO), propylene oxide (PO), 1-ethoxyethyl glycidyl ether (EEGE) and/or glycidol. |
