Crystal growth inhibition

In summary, dispersants are effective for particle dispersion and crystal growth inhibition, but do not normally have surface-active properties such as oil emulsification. Chelants and antiprecipitants frequently inhibit crystal growth better than dispersants, but are ineffective for particle dispersion. Flocculants are effective for aggregating particles, the opposite function of a dispersant. 

Other explanations of the DR effect can be offered, as has been suggested by Collet.24 It is also not unlikely that various effects, likely complementary, are involved. For instance, nucleation inhibition and crystal growth inhibition can play an important role during many DR experiments...

The crystallization in PEO/PMMA blends is influenced by the nature of the casting solvent. Phase segregation in the blend and PEO crystal growth inhibition by PMMA in certain directions have been observed in these miscible blends [Radhakrishnan and Venkatachalapati, 1996]. In PET/PC blend (Makroblend 4T 1018), the chemical and solvent influences are improved, compared to constituent polymers. The chemical resistance of this blend is shown in Table 12.17 [Mark et al., 1988]. 

Research on the use of tailor-made surfaces for promotion of nucleation has been pursued in parallel with studies of crystal growth inhibition [35,36]. The objective here is to gain a deeper understanding of the mechanism of molecular...

For the same purpose of targeting bone tumors with boron-containing phosphonates, carbabora-nylbis- and -polyphosphonic acids were described by Benedict in a patent application. Two examples of the prepared compounds (37, 38) are shown in Figure 2.4. The gcm-bisphosphonate 37 was subjected to a crystal growth inhibition test to determine its potential to reduce calcium phosphate deposition. This showed that the capability of 37 to retard the formation of calcium phosphate is on the same order as the known inhibitor dichloromethylene diphosphonate. Furthermore, it was found to exhibit high skeletal affinity in an animal skeletal uptake test.
