1. A polyamide comprising recurring units X and Y and represented by the following formula (1):

OG Complex Work Unit Chemistry
wherein
nx and ny are respectively the mole percent (mol %) of each recurring unit X and Y;
15 mol %≤nx≤90 mol %;
5 mol %≤ny≤90 mol %;
95 mol %≤nx+ny≤100 mol %; and
wherein
R2 is selected from the group consisting of a C1-C15 alkylene and a C6-C30 arylene;
R3 is selected from the group consisting of a C1-C20 alkylene, a phenylene, an indenylene, and a naphthylene;
with the provisos that
if recurring unit Y is formed from the condensation of p-xylylene diamine and a C12 dicarboxylic acid then:
30 mol %≤nx≤90 mol %;
5 mol %≤ny≤70 mol %;
nx+ny≤100 mol %; and
if recurring unit Y is formed from the condensation of terephthalic acid with a diamine, R2 is selected from the group consisting of a C1-C9 alkylene, a C11-C15 alkylene, and a C6-C30 arylene.
