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. WebIt has one four-fold axis of symmetry. A cubic crystal, such as galena, halite, pyrite, fluorite or sphalerite, can be likened to a single sugar cube. All edges are the same, and all angles are at 90 degrees. It has four three …
