摘要:
A method of (co)polymerizing vinyl and/or diene monomers comprising contacting the monomers with a (co)polymeriztion composition under conditions effective to (co)polymerize the monomers, wherein the (co)polymerization composition comprises: (a) an organic peroxide component, and (b) a heteropoly acid, in an amount effective to lower the onset temperature of decomposition of the organic peroxide component with the proviso that if the heteropoly acid is phosphomolybdic acid the organic peroxide is not a peroxydicarbonate.
摘要:
Bio-based biocide compositions containing epoxidized 2-ethylhexyl soyate and a solvent such as epoxidized soybean oil are disclosed. When incorporated into polymers such as PVC, preserved polymer compositions result. The invention also provides methods for preserving polymers, including incorporating these compositions into PVC in accordance with these methods.
摘要:
Bio-based wax compositions contain at least one of the following components: epoxides of non-hydrogenated vegetable oils, epoxides of fatty acid esters. epoxides of tall oil fatty acid esters, chemically modified epoxides of non-hydrogenated vegetable oils, chemically modified epoxides of fatty acid esters, and chemically modified epoxides of tall oil fatty acid esters. The wax compositions can be used to produce candle sticks, container candles and/or composite materials.

Bio-based wax compositions contain at least one non-hydrogenated epoxy product and at least one wax component containing insect wax. The wax compositions can be used to produce candle compositions such as free-standing candles and container candles, and/or composite materials.
摘要:
Disclosed herein are compounds of the formula: (R)x—Sn—(R′)4-x wherein: R is alkyl; R′ is a moiety selected from the group consisting of: w is 0 or 1; x is 1 or 2; y is 1, 2, 3, or 4; and Z is a linear, branched, cyclic, or aromatic hydrocarbon. These compounds are excellent stabilizers for halogen-containing resins, such as PVC.
摘要:
A composition is disclosed that comprises: (A) at least one polymer selected from the group consisting of polyolefins, polar polymers, and mixtures thereof; and (B) a graft copolymer comprising a propylene polymer backbone having grafted thereon at least one monomer selected from the group consisting of alkyl(meth)acrylates and vinyl aromatic compounds, said graft copolymer having been prepared by a solid state grafting process comprising blending a solid propylene polymer with said monomer(s) in a reactor in the presence of a free radical-generating means and reacting the polymeric components at elevated temperature in the absence of solvent.
摘要:
Disclosed herein is a composition comprising: A) at least one component selected from the group consisting of: 1) unsaturated polyester resins; and 2) organic peroxide initiators; and B) and at least one dye that is compatible with any organic peroxide present and is selected from the group consisting of anthraquinone derivatives, pyrazalone derivatives, and mixtures thereof.
摘要:
Disclosed herein is a process for improving mechanical properties and thermal stability of composites of poly(vinyl chloride) and at least one natural fiber comprising including in said composite an agent comprising a polymer or copolymer comprising at least one alkali metal salt of at least one polymerized ethylenically unsaturated carboxylic acid. Articles of manufacture comprising the stabilized PVC are also disclosed.
