Abstract: A degradable EVOH high-barrier composite film, characterized in that the materials of various layers in the composite film all obtain approximately-consistent biodegradability by introducing biomass, and the additive amount of the additive master batch in the materials of each layer is controlled within the range of 0.3-15% of the total mass of the materials of the corresponding layer; the hydrophilic activity of the hydrophilic groups in the additive master batch should be greater than or equal to that of the hydrophilic groups in the materials of each layer; by adding the additive master batch, the mole ratios of the hydrophilic groups to carbon atoms of the materials of various layers tend to be consistent, namely, the bioactivities tend to be consistent, so that the degradation rates of the materials of various layers in the composite film tend to be consistent. The present invention makes contribution to obtaining approximately-consistent bioactivities and approximately-consistent biodegradation rates by balancing the mole ratios of the hydrophilic groups to carbon atoms in the materials of various layers, and the appearance, the functions and the physical and mechanical properties of a product remain unchanged.

Abstract: Compositions and methods of making a modified polyhydroxylated polymer comprising a polyhydroxylated polymer having reversibly modified hydroxyl groups, whereby the hydroxyl groups are modified by an acid-catalyzed reaction between a polydroxylated polymer and a reagent such as acetals, aldehydes, vinyl ethers and ketones such that the modified polyhydroxylated polymers become insoluble in water but freely soluble in common organic solvents allowing for the facile preparation of acid-sensitive materials. Materials made from these polymers can be made to degrade in a pH-dependent manner. Both hydrophobic and hydrophilic cargoes were successfully loaded into particles made from the present polymers using single and double emulsion techniques, respectively. Due to its ease of preparation, processability, pH-sensitivity, and biocompatibility, of the present modified polyhydroxylated polymers should find use in numerous drug delivery applications.
