Abstract : Soy protein plastic formulations were developed through iterative experimental stages to produce waterstable, soy protein isolate (SPI)-based plastic resins. The protein polymer-based materials are glycerol and
water plasticized resins that have been described as thermoplastics [1] by some researchers and have been
described as materials that behave similar to thermoplastics upon application of heat and pressure [2].
Previous researchers have developed SPI plastic for various applications, all of which were adversely effected
by water absorption. The formulations in this research included anhydride chemistries, such as maleic
anhydride (MA), phthalic anhydride (PA), and bifunctional chemistries, such as adipic acid in… More >
