Polymer Crystals
Polymer crystals gel very similar to a gelatin dessert.
Polymer crystals. Melt crystalline and amorphous 15. Thus the behavior of polymers can better be understood in term of the three phases. The length of polymer molecules also makes it difficult for the large crystals found in the solid phases of most small molecules to form. The polymers allow for thinner and lighter disposable diapers.
Instead solid polymers can be modeled in terms of two phases crystalline and amorphous. One of their major uses is by the disposable diaper manufacturers where they are referred to as super absorbent polymers. Polymers can crystallize upon cooling from melting mechanical stretching or solvent evaporation. Polymers are large molecules with strong intermolecular forces and tangled chains and do not have a vapor phase they decompose before the temperature gets high enough to form a vapor.
Crystallization affects optical mechanical thermal and chemical properties of the polymer. Most small molecule behavior can be understood in terms of three states. Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae which compose larger spheroidal structures named spherulites.
