The present invention relates to polymer compositions comprising at least one basic additive, and processes comprising at least one process step to obtain the polymer composition or articles comprising the polymer composition. The polymer composition generally displays an enhanced biodegradability.

Described are dissolvable, porous solid structures formed using certain vinyl acetate-vinyl alcohol copolymers. The copolymer and the porosity of the structure allow for liquid flow during use such that the structure readily dissolves to provide a desired consumer experience. Also described are processes for making open cell foam and fibrous dissolvable solid structures.

A resin molding method is capable of reducing the use amount of micropellets and obtaining a resin molded article having required characteristics. A resin molding method includes a disposing step of disposing a preliminary molded body laminated and formed in a three-dimensional shape in a molding die, a filling step of heating and melting the preliminary molded body by an electromagnetic wave transmitted through the molding die and filling the molding die with a molten resin material, and a cooling step of cooling and solidifying the molten resin material in the molding die. In the cooling step, a resin molded article integrated so as to eliminate a lamination interface of the preliminary molded body is formed in the molding die.

Embodiments relate to a polyamide-imide film that secures excellent tensile toughness and elastic restoring force, and a process for preparing the same. The polyamide-imide film comprises a polyamide-imide polymer formed by polymerizing a diamine compound, a dianhydride compound, and a dicarbonyl compound, wherein the area value up to the yield point derived by the 0.2% off-set method on a stress-strain curve of the polyamide-imide film as measured using a universal testing machine (UTM) is 80 to 150 J/m.sup.2.

The invention provides a composition comprising a seaweed extract in an amount of 50-90% by weight, a water-soluble cellulose derivative in an amount of 10-40% by weight and water in an amount of 1-20% by weight, of the total weight of the composition. The invention also provides products, including packaging material, formed from the composition, a method of dissolving, composting and biodegrading the composition or the products, a method of producing the composition and the products, and a method of re-working the composition.

Embodiments of the present invention describe a method for manufacture of a gel material comprising the steps of: forming a gel sheet by dispensing a gel precursor mixture; allowing gelation to occur to the gel precursor mixture; and cooling the formed gel with a cooling system to control reaction rate.

The present disclosure provides a curable casting resin precursor, comprising (a) a first part (A) comprising: (a1) at least one epoxy resin; (b) a second part (B) comprising: (b1) at least one first amine-based epoxy curing agent; (b2) optionally, at least one second amine-based epoxy curing agent; (b3) at least one mineral filler; (b4) at least one phenolic lipid; wherein part (A) and/or part (B) comprise at least one triphenylmethane dye. The curable casting resin precursor is suited for encapsulating metal parts such as cable joints and the like.

The present invention relates to a fishing bait, a mouldable composition for manufacturing the fishing bait, a method for manufacturing the fishing bait and a use of the mouldable composition. The mouldable composition comprises a basic solution comprising water, a gelling agent and a plasticizer. The mouldable composition further comprises at least one cross-linking agent in the volume of the basic solution.

Disclosed are an electronic candle structure and production method, and wax shell of the electronic candle. The electronic candle, comprising a wax shell, an core system and a lining, the wax shell is formed by directly cooling and solidifying melted wax on the outer surface of the lining, the outer surface of the wax shell is formed by the inner surface of a female mold, and the main body of the core system is fixed in the inner space of the lining. Compared with the prior art, the invention greatly reduces the consumption of raw materials and energy in the production process, shortens the production cycle, improves the production efficiency, and effectively reduces the costs. Moreover, the overall mechanical strength of the product is enhanced to prevent the product from deformation under the long-term use conditions at relatively high environmental temperatures, and improve the durability of the product.
