Carbon black and silica are well known reinforcing fillers in rubber compounds and these, as well as other fillers, are often used as fillers for polymeric compounds in other industries, such as in thermoplastics, composites, paint, and the like. In rubber, attempts at improving filler dispersion have included high temperature mixing of carbon black-rubber mixtures in the presence of selectively-reactive promoters to promote compounding material reinforcement. 3: Dispersion Agents (4) Compound 4-(2-oxazolyl)-phenyl-N-methyl-nitrone (40PMN) 4-(2-oxazolyl)-phenyl-N-phenyl-nitrone (4OPPN) 4-(2-thiazolyl)-phenyl-N-methyl-nitrone 4-(2-thiazolyl)-phenyl-N-phenyl-nitrone 4-(2-oxazolyl)-phenyl-N-methyl-nitrilimine 4-(2-thiazolyl)-phenyl-N-methyl-nitrilimine minal end of polymers using, for example, N,N,N’,N’-tetramethyldiamino-benzophenone (Michler’s ketone), tin coupling agents, etc.
Favorable compounds are citrate plasticizers. These are biodegradable esters. Poly(1acticacid)s (PLA)scan be softened, for example, by adding plasticizers, blending soft polymers, or carrying out copolymerization. However, when blending soft polymers, usable soft polymers are limited to biodegradable resins such as poly(buty1ene succinate) from the view point of biodegradability. Such biodegradable resins have to be added in large quantities to impart sufficient flexibility, and the addition in large quantities may impair this characteristic of PLAs.
Copolymerization changes the physical properties such as melting point and heat resistance, owing to the decrease in crystallinity and glass transition temperature (38). PLA has been extensively studied in medical implants, suture, and drug delivery systems due to its biodegradability. The synthesis of several mixed alcohol esters has been described in the literature (38). PLA has been plasticized with four commercially available citrate plasticizers: triethyl, tributyl, acetyltriethyl and acetyltributyl citrate (39).
