Synthesis and Application of Reactive Acrylic Latexes: Effect of Particle Morphology.

The aim of the study is the synthesis and characterization of epoxy functional reactive polyacrylic latexes, e.g., poly (BA-co-MMA-co-AN-co-GMA) with core/shell and non-structured (random) particle morphologies.

Possible use of corn starch as tanning agent in leather industry: Controlled (gradual) degradation by HO.

High molecular weight/size and poor solubility of native starch seems to be preliminary drawbacks in its possible use in leather processing as a tanning/retanning agent. For this purpose, firstly the native starch which has too large molecular size to penetrate between skin fiber matrix was oxidized with HO in different molar ratios for disintegrating into appropriate molecular size that can be used in tanning process. Then, the product yields, water solubilities and degree of substitutions of oxidized starches were determined.
