Coatings are multi-component systems and surfaces/interfaces have a strong influence on their quality and play also an important role during paint application. Coating additives are used since many years successfully as "problem solvers" in coating formulations to overcome defects and in general to improve the overall quality. Many coating defects are closely connected with interfacial phenomena and therefore it is no surprise that oftentimes coating additives are surface active materials. Examples of typical coating defects are shown together with problem solutions using surface active coating additives. The development of coating additives is mainly driven by market needs. In the past excellent quality and performance had a very high priority. During the last 15 to 20 years the focus shifted more and more to ecological considerations. Less pollution of water and air is required and the range of raw materials from which the paint chemist can choose has shrunken (e.g., no more lead pigments, no more aromatic solvents). These changes are a constant challenge for additive producers. Coating additives normally do not trigger new developments in coatings but they can be the crucial factor to make a new and innovative coating system successful in the market.

ABSTRACT:This work compares different calibration models for the estimation of monomer concentrations by Raman spectroscopy during semicontinuous emulsion copolymerization reactions. The limitations of these models are discussed in terms of a complex reaction, namely the copolymerization of vinyl acetate and butyl acrylate, whose monomers present overlapping Raman spectra, especially the CϭC stretching band. Additionally, the copolymerization was monitored in a spectroscopic setup arranged for fast spectral acquisition, which resulted in a low signal-tonoise ratio. These realistic conditions for in-line monitoring of emulsion copolymerization, i.e., considerable noise level in the spectra and medium heterogeneity, are discussed in the context of different approaches for adjusting the calibration model and the ensuing model limitations. It was verified that combining data obtained during reactions with synthetic samples is interesting from the statistical point of view, since in this way it is possible to produce data sets with a wide range of variation, allowing the accurate estimation of statistical parameters. These parameters are of major importance for process variables and product property estimations, especially if they are to be used for process control and decision making purposes.

“…From Figs 1 and 2, and previous reports, the wavenumbers, at 1000, 1668 and 3053 cm 1 can be assigned to ring breathing, C C stretch and CH stretch of styrene and butadiene, respectively. 4,6,15,18 The wavenumbers at 1732 and 2239 cm 1 may be due to C O stretch of methyl methacrylate and C N stretch of acrylonitrile. 4,6,15 The broad peak around 3300 cm 1 can be assigned to the OH stretch of water present in the latex emulsions since drying of the emulsions caused a weakening of this peak [ Fig.…”

Vibrational spectroscopy is utilized to characterize compounds, but it has never been applied to quantitative morphological analysis of polymers in a mass. By using near-infrared Fourier transform Raman spectroscopy coupled with multivariate data analysis, the average particle diameter of macroscopic size in water-based latex emulsions was successfully quantified with correlation coefficients >0.95, both in calibration (known samples, n = 36) and in prediction (unknown samples, n = 11) against conventionally measured values obtained by the dynamic laser diffraction scattering method. This method is valid for samples of various monomer compositions together with various fluorescence and Rayleigh scattering intensities causing different background levels in the spectra.
