The invention disclosed herein is a process of obtaining starch betainate, a more biodegradable alternative to cationic starch ethers. Starch betainate is obtained by transesterification in solution with an aprotic solvent or in a dry medium with a ball mill. Betaine hydrochloride is first esterified with thionyl chloride and methanol. The starch is then converted to starch betainate in aprotic solvents, using a strong acid as a catalyst or a pre- activation of the polymer in a basic medium. Regarding the transesterification in a dry medium, this pre-activation of the polymer is also carried out in a basic medium, while in an acid medium only a solid acid is used in the reaction. The invention also relates to the use of the starch betainate obtained by the presented process in the production of paper material, as well as to any paper material that includes the starch betainate produced by the process described in this invention.

A microwave popcorn bag for containing and heating popcorn kernels in a microwave oven. The bag is constructed of a laminated fibrous material and comprises a base panel, top panel, side panels, and interior space. The side panels have gussets with fold areas and fold lines that are adjacent to the base panel and that enable the bag to expand. An oil-resistant microwave susceptor film is laminated with the fibrous material and extends laterally across the base panel and the fold lines into the fold areas. Microwave interactive material is confined to the base panel. As the popcorn is heated, the bag expands and the microwave susceptor film forms a tray structure that collects oil and resists it penetrating through the fibrous material.

A method includes mixing a dry hydrophobic material with a dry superabsorbent polymer to improve the flowability of the polymer in humid conditions within a machine passageway having a residency time. The application of superabsorbent polymers in agriculture is desirable to aid plant growth in increasingly hot and dry conditions. However, dry bulk planting applications typically used in agriculture require the dry amendment to pass through confined channels and narrow pores. This is problematic because the polymers rapidly absorb moisture from the environment and adhere to the planting equipment causing fouling and clogging. The improvement in flowability provided by the compositions disclosed herein, is to the extent that the superabsorbent starch-like polymer can be applied using dry bulk planting applications in the humid conditions of Florida in the springtime. Surprisingly, the dry mixtures improve flowability without undermining the ability of the polymers to rapidly absorb moisture from rain.

A system for delivery of fragile payloads involves a structure having an approximately spherical aspect composed of rigid struts and flexible tendons joining ends of struts, the flexible tendons in tension placing the struts in compression, the structure having a hollow interior, and one or more fragile items wrapped in a shock-absorbing bio-degradable material such that no fragile item contacts another, forming a payload bundle, the payload bundle joined by fibrous filaments suspending the payload within the structure. The structure carrying the payload bundle is carried to a destination by an aerial vehicle and dropped from a height to the ground, where the structure rebounds and rolls, dissipating kinetic energy gained in falling, preventing the payload bundle from striking ground surface.
