Abstract
Amino acid functionalized polymers useful for graft copolymerization prepared by reacting a mixture containing, for chain transfer, a thio-substituted amino acid and an ethylenically unsaturated monomer.
Claims14
A method of preparing an amino acid functionalized macromonomer composition having a degree of polymerization of from about 5 to about 20,000 comprising reacting by free radical polymerization a mixture comprising:
- (a) for chain transfer, an amino acid having the formula:
- 3
- wherein:
- R1 and R2 are H or CH3;
- and
- Z is alkylene or arylene;
- and
- (b) at least one polymerizable ethylenically unsaturated monomer, such that, as a result of reacting said mixture, at least 10 mol percent of the macromonomer composition product has the end group:
- 4
An amino acid functionalized addition-polymerized macromonomer composition having a degree of polymerization of from about 5 to about 20,000.
