Table 1.

Molecular weight and amino content of HBP-NH₂ where the amide content (mmol/g) of HBP-NH₂ was calculated from the oxygen mole content, alkyl amino content of HBP-NH₂ was calculated by subtracting the amide content from total amino amount.

Mw (g/mol)	C (wt%)	N (wt%)	H (wt%)	O (wt%)	Amino amount (mmol/g)	Amide content (mmol/g)	Alkyl amino content (mmol/g)
