32-35 The following is an abstract of a published paper. Read it through and look for the following purpose of the sentences.
Abstract:
A) The present research examines how the molecular weight of PAA affects its influence on the crystallization of CaCo3. B) Factors of calcium concentration and temperature were monitored in heated supersaturated solutions containing PAA samples which raise the temperature necessary to induce crystallization. C) Testing of mixed molecular weight distributions demonstrated that high molecular weight species govern the observed inhibition influence. D) An equation was also developed for predicting the influence of a mixed molecular weight distribution on crystallization temperatures at unsaturated surface conditions, assuming each polymer species produces a specific crystallization temperature. E)The microstructure of these crystals indicates the roughness results from the aligned aggregation of crystallites on the surface of existing crystals in a process that resembles a form of self-assembly.
