Abstract: A reactant composition for forming a polymer via metal-free ring-opening metathesis polymerization may comprise a stabilizer, a stabilizing reactant comprising a stabilizing moiety covalently bound to a reactant moiety, or both; wherein the stabilizer is a halogenated alcohol and the stabilizing moiety is derived from a halogenated alcohol. The reactant composition further comprises a strained cyclic unsaturated monomer; an initiator; a mediator; and optionally, one or more of a co-monomer, a crosslinker, and a chain transfer agent.

Abstract: Disclosed is a smokeless stove. The smokeless stove includes: a stove body having a combustion chamber, openings and a combustion disc are provided in the combustion chamber, the combustion disc is provided with several first ventilation holes, an ash storage disc is hung on the combustion disc and separated from the combustion disc, at least one hook ring is fixedly arranged in the combustion disc, and several air inlet holes are provided in the stove body. The combustion disc is arranged in the stove body, the ash storage disc is separated from the combustion disc, and the hook ring is arranged in the combustion disc, such that the combustion disc and the ash storage disc are conveniently hooked and taken out by a fire hook, so as to improve cleaning convenience; and the stove body is integrally formed, so as to improve production efficiency and simplify production procedures.

Abstract: Disclosed is a secondary combustion structure of a smokeless stove. The secondary combustion structure includes: a stove body, a combustion disc and an inner wall arranged in the stove body, several separated first ventilation holes are provided in the combustion disc, a heating chamber is defined by the inner wall and the stove body, several second ventilation holes are provided in the inner wall, and an air inlet hole is further provided in the stove body. With the design, heated air flows out of the second ventilation holes to support combustion of combustible gas, further secondary combustion is achieved, a combustible is combusted more sufficiently, and smoke is reduced; and moreover, a top of the stove body is inclined towards the inner wall, so as to increase a flow speed of the heated gas, and increase a fire behavior of the combustible.

Abstract: Disclosed is an inner tray structure of an open fire oven. The inner tray structure of an open fire oven includes an oven base; a grill, an oil drip tray and an ash cleaning tray are mounted on the oven base in turn from top to bottom; the ash cleaning tray is provided with holders, a top of one holder is provided with a handle, and the oil drip tray abuts on the holders; and other components. The oil drip tray and the ash cleaning tray can be taken out conveniently and quickly together, and charcoal ash and grease can be stored and separated in an oven as well.

Abstract: Disclosed is a handle locking structure of an open fire oven. The handle locking structure includes an oven base, where an upper end surface of the oven base is provided with a clamping recess; an upper cover, where the upper cover is rotatably mounted on the oven base, a joint of the upper cover and the oven base is opposite the clamping recess in position, a side surface of the upper cover is provided with a mounting recess, a handle is rotatably mounted on the mounting recess, and the handle fits the clamping recess; and the handle is provided with a clamping flange, the clamping flange being clamped in the clamping recess or released therefrom by rotating the handle; and other components. Consumers can unlock and open the upper cover conveniently and quickly, and lock the upper cover conveniently as well.
