摘要： This invention provides a flame retardant additive composition which comprises at least one glow suppressant and at least one brominated flame retardant. The glow suppressant is about 0.5 wt% or more of the flame retardant additive composition, based on the total weight of the flame retardant additive composition. The brominated flame retardant contains aromatically-bound bromine and is selected from a) a brominated anionic styrenic polymer having a number average molecular weight of about 750 to about 7500, and/or a bromine content of about 60 wt% to about 77 wt%, b) a brominated anionic chain transfer vinyl aromatic polymer which contains about 70 wt% or more bromine, or a mixture of any two or more of these. Also provided are flame retarded polyolefin compositions that contain at least one glow suppressant and a brominated flame retardant.

摘要： A copolymer composition including a method having a first step involving submerging of LDPE into a heptane bath and heating the heptane bath until the LDPE dissolves into the heptane bath resulting in a water-like solution. A second step including precipitating of the water-like solution forming a PE wax within the water-like solution. A third step involving filtering and distilling of the water-like solution separating the PE wax from the heptane bath. A fourth step involving dispersing of the PE wax in a liquid carrier resulting in a combination. A fifth step involving polymerizing of the PE wax into LDPE by introducing the combination into PVA during an extrusion process resulting in a homogeneous mixture. A sixth step, programming the water solubility of the homogeneous mixture. Resulting in the copolymer composition having programmable water solubility, shelf-life stability and quality in the presence of moisture for a predetermined length of time.

摘要： A method of separating and purifying a mixed stream of contaminated reclaimed polyethylene and contaminated reclaimed polypropylene is provided. The method comprises the steps of extraction, dissolution, settling, purification, and solvent separation to produce separate streams of purified recycled polyethylene and purified recycled polypropylene. Both separate streams are produced in the same production plant operating in swing mode, and have virgin-like optical properties.
