WebPolymers can exist as both crystalline and amorphous solids. In fact, most polymers are semicrystalline, which means that they contain a mixture of crystalline and amorphous … WebFor example, there are three polymorphs (same chemical formula, different crystalline structures) of calcium carbonate that are known as calcite, aragonite and vaterite. Calcite crystals occur in the trigonal system, aragonite crystals belong to the orthorhombic system and vaterite crystals form in the hexagonal system.
