k1k1 bro is trying to promote something that is flopping severely 💀💀.
i don’t understand a single ounce of chemistry so what i might suggest is wrong, but you could formulate your research question as ‘how do green polymers (factors) compared to synthetic polymers?’ it’s a little difficult because you’re claim is really broad by using the term ‘better.’
as i said, i have no chemistry knowledge in my brain, but if you were talking about the organic-ness, you could claim that ‘green polymers are more organic than synthetic polymers’ and your research question could be ‘how are green polymers more organic that synthetic polymers when (factors) are tested?’
but instead of organic (unless i am correct and should pursue a chemistry phd 😒) replace it with the overall thing you intend to measure. hope that makes sense and it wasn’t a lot of yap T-T
