ABSTRACT:
Compatibilizing agents suitable for blending otherwise immiscible polymers comprise a block or graft copolymer in which at least one of the block segments is formed by a living anionic polymerization and thereafter chemically converted to provide a polymer having at least one functional end group. The functional groups of the polymer blocks thus formed are reacted with a functionalized monomer, or an oligomer to provide a second block polymer segment. Compatibilizing agents containing more than two blocks may be formed in similar fashion. The compatibilizing agents are used to provide uniform blends of polar and non-polar polymers having superior uniformity and other physical properties.
