| titleOfInvention | Block copolymers and process for their preparation |
| abstract | Under particular conditions, a cationic ring-opening polymerization of an (single) oxirane monomer selected from the group consisting of an acyclic glycidyl ether, a cyclic glycidyl ether, and a haloalkyl epoxide, in the presence of a hydroxyl-terminated prepolymer ("HTP") and a particular catalyst, produces a polymerization having 'living polymerization' characteristics, provided that the OH groups are aliphatic OH groups and not aromatic OH groups. The result is an AB or ABA type block copolymer the molecular weight (mol wt) of which is directly proportional to the conversion of the monomerto the block copolymer. The HTP which may be a mono-, di-, tri-, or tetra-hydroxyl-terminated prepolymer, serves as a chain propagator which initially furnishes OH groups as propagation sites. Linear block copolymers or branched block copolymers are formed, depending upon the structure of the HTP. Where one segment of an AB or ABA type block contains halogen, the segment may be aminated. If the other segment is hydrophobic, the aminated block copolymer is amphiphilic. |
