DEFINITION

Classification: 525/54.11

Solid polymer treated by stepwise reaction with naturally occurring alpha or beta amino acid or a material which contains a residue of said amino acid, e.g., a functionally protected amino acid, etc.:

(under subclass 54.1) Subject matter wherein the biologically active polypeptide is generated by stepwise treatment of a preformed solid polymer with a naturally occurring alpha or beta amino acid or a material which contains a residue of said amino acid, or product of such a process.
