PVA vs. PVAc / Slime question

Hello!

I'm a slime hobbyist and I don't fully understand the science behind slime, glue, PVA, PVAc, etc. I get the basics, but I'm still confused on PVA vs PVAc.

I read on the chemistry subreddit that PVA is actually polyvinyl alcohol and PVAc is polyvinyl acetate. However, I see a lot of these used interchangeably on YouTube and slime shops. There's one slime shop that says their slime contains "polyvinyl acetate (PVA)"— am I missing something? I ready that (I think) PVA can turn into PVAc (or maybe it was the other way around?).

It's difficult for me to find a lot of slime science material that either isn't too basic (for kids) or easily digestible and engaging for someone not familiar with chemistry (very dry). It's very interesting stuff. I've also been trying to understand water slime and glue specific to making water slime. I read there's different PVA (or PVAc, I don't know anymore I'm so confused lol) solutions with different viscosities that are more water-soluable. It's difficult to find the science behind it though, as most YouTube videos are about super glue or generic glue science videos.

If anyone could direct me to an easy to read source so I could better understand chemistry or chemistry related to slime, I would really appreciate it. Chemistry for Dummies? or where to start I would appreciate it! I'm afraid to fully understand it I might just need to study intro to chemistry, which I know is very complex, and probably out of my league.

Thanks for anyone's help!
