Web2) Test the purity of the synthesized crystals. 3) Analyze the synthesized crystals and predict its formula using methods such as: titration, spectrophotometry, and determination of percent hydrate. Introduction One of the most exciting aspects of chemistry is the ability to synthesize new materials. WebSep 7, 2024 · Crystalline Polymers. Highly crystalline polymers are rigid, high melting, and less affected by solvent penetration. Crystallinity makes a polymers strong, but also lowers their impact resistance. As an example, samples of polyethylene prepared under high pressure (5000 atm) have high crystallinities (95 - 99%), but are extremely brittle 21.
