每個monomer 至少要有兩個functional groups
咁呢兩個functional groups係咪一定要一樣?

唔一定要一樣
eg. urea methanal - aldehyde (-CHO) and amine (-NH2)
methanal is H-CHO , 佢都冇兩個functional group ga...
eg. nylon-6
one carboxylic acid (-COOH) and one amine (-NH2)
H2N-(CH2)5-COOH (希望你睇得明佢個structure)

sorry, methanal has no amine, 打多左
