Questions about the Polymers poster

What’s on the Polymers poster?

Addition against Condensation, side by side. Addition: Monomers with C=C; Addition: No by-product; Addition: Repeat unit has the same formula as the monomer; Addition: Poly(ethene), poly(propene), PVC; Addition: Chemically inert; hard to break down; Condensation: Two functional groups per monomer; Condensation: Loses water or HCl; Condensation: Polyesters, polyamides; Condensation: Nylon, terylene, proteins; Condensation: Can be hydrolysed; Condensation polymers are biodegradable because the ester or amide links can be hydro…. Draw a repeat unit with the bonds extending beyond the brackets and n outside. Both details are marked.

Who is the Polymers poster for?

Polymers belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning organic can pin it up — a beginner, a student mid-course, or someone revising years later.

When should you use the Polymers poster?

Addition loses nothing. Condensation loses a small molecule each time. A wall chart earns its place by being glanceable from where the work is happening, so Polymers belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.

What other posters go with Polymers?

Alcohols, Alkanes and Alkenes sit alongside Polymers in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AlcoholsAlkanesAlkenes

Is the Polymers poster free to download and print?

Yes. Polymers downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence

What size does the Polymers poster print at?

Polymers is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Polymers loses nothing.Printing guide
