This invention relates to new destructured starch derivatives and elastomer compositions containing them. In particular this invention relates to destructured starch silyl ethers in which at least one oxygen atom of the destructured starch is covalently bonded to at least one silicon atom and/or to at least one compound containing silicon.

A laminate comprising: a gas barrier layer (I) comprising a modified starch (A) having an average amylose content of 45% by mass or more and a water-soluble polymer (B); and a substrate (II) adjacent to the gas barrier layer (I), wherein the laminate exhibits a degree of biodegradation of 80% or more in a biodegradability test in accordance with ISO 14855-1.

A halogenated polysaccharide is provided having a halogen content of from about 1.0 wt. % to about 85 wt. % based on the total weight of the halogenated polysaccharide and having an average chain length of at least 6 monosaccharides. Methods of halogenating a polysaccharide to form a halogenated polysaccharide are provided that can be performed in the presence or absence of a proton solvent. Compositions such as articles of manufacture containing a halogenated polysaccharide and methods of producing such articles are also provided. The article of manufacture can also include one or more additional polymers, for example, polyvinylchloride (PVC). The article of manufacture can be, for example, a flooring tile, flooring plank, or carpet. Halogenated polysaccharides and products containing the same are bio-based, environmentally sustainable replacements or complements to existing polymers and polymer products.

The present invention concerns a method for modifying a polysaccharide material, preferably an amylaceous material, involving a first step of homogeneous solubilisation of said polysaccharide material in an aqueous solvent, followed by a step of homogeneous chemical functionalisation comprising at least one non-crosslinking chemical modification, or at least one crosslinking chemical modification, or a sequence of at least one non-crosslinking chemical modification and at least one crosslinking chemical modification. Secondly, the present invention concerns a modified polysaccharide material, in particular obtained by the method according to the invention, characterised in that it has a novel distribution of the chemical substituents attached to the hydroxyl functions of the anhydroglucose units of said polysaccharide material. The novel starches can be used as organic adjuvants for dry mortars made from cement or made from gypsum, in particular as a binder for a dry mortar made from cement or as a thickening agent for a mortar made from plaster.
