Poly cellulose acetate butyrate blends

Carboxylated polyesters were prepared by extending hydroxyl-terminated polyester segments with dianhydrides. Carboxylated polyesters which were soluble in common lacquer solvents were effective in improving the adhesion of coatings on a variety of substrates when 1-10% was blended with cellulose acetate butyrate, poly(vinyl chloride), poly(methyl methacrylate), polystyrene, bisphenol polycarbonates, and other soluble polymers. 

Table II shows the effect of the carboxyl content on the adhesive characteristics of PMDA-extended polyesters in blends with K-l polycarbonate [4,4 - (2-norbomylidene) diphenol polycarbonate] (VIII), cellulose acetate butyrate, and poly (vinyl chloride). K-l polycarbonate is an experimental polymer which, like cellulose acetate butyrate and poly (vinyl chloride), is very sensitive to adhesive changes because only 1-2% of a carboxylated...

There is concern as to why this particular blend behaves so differently from those illustrated in Figs. 11.10 and 11.11. Other blends such as poly(ethylene oxide)-poly(vinyl acetate),(28) poly(3-hydroxy butyrate)-cellulose acetate butyrate,(29) poly(3-hydroxybutyrate)-poly(ethylene oxide) (30) and poly(3-hydroxybutyrate)-... 

Consequently, the intermolecular interactions of the blends of cellulose alkyl esters, such as cellulose acetate and cellulose butyrate, with different polymers have been investigated, the conclusions of such studies being that the miscibility state in the cellulose ester/poly[(N-vinylpyrrolidone)-co-(vinyl acetate)] or poly[(N-vinylpyrrolidone)-co-(methyl methacrylate)] product is due to the balance among different attractive interaction based on [132] ...
