4.1 A sample of atactic poly(vinyl alcohol) is known to have 60 wt% crystalline regions and 40 wt% amorphous regions. A. Draw the repeat structure of poly(vinyl alcohol), PVA? B. Is this polymer made by free radical or condensation polymerization? C. What type(s) of weak bonds would you expect to help with forming crystals in PVA? D. Copolymers of poly(vinyl acetate), PVAc, and poly(vinyl alcohol) are used in latex paints. What is the role of this copolymer in latex paint? (Use the internet- the Macrogalleria has a nice explanation; side note: Latex paints are commonly used for home interior painting) 60amatallinitu?
