This study is part of saponification of polyvinyl acetate and natural polymer potato starch, both difficult to co-glue, and join the natural polymer wheat starch co-glue research. Part of saponification of polyvinyl acetate to the dissolution of the hot water bath, add the glycerin, and gelatinized starch blends dry respective fields due to these two materials, biodegradable, so you can explore the nature of the decomposition of material hardness and students before and after the decomposition nature.
Plastination, the first in the same glycerol (4%) intended on the part of saponification of polyvinyl acetate (8-14%) / the thermoplastic gelatinized starch (5-20%) co-glue together plastic uneven distribution of and then in the potato starch, wheat starch. The nature of the analysis. Join the wheat before the non-linear distribution of tensile stress by adding wheat, the tensile stress is linearly distributed. FTIR and hardness test before joining the wheat, the graphics are not perfect, by adding wheat to strike a balance, co-gel structure. Thermal analysis, graphics can be found in this study co-gum, there are still non-perfect curve. Fixed PVAc, pyrolysis temperature rise in direct proportion with the starch proportion. Finally glue made PVAc12% and starch together, found the same with full saponification of PVA biodegradable differences, this study is to use part of saponification of PVAc not easily biodegradable plastics composites.
