    摘要: A husk plastic composite comprises a composition including: PVC 10˜20 wt %; vinyl chloride/vinyl acetate (VC/VAC) copolymer 10˜30 wt %; styrene-acrylonitrile copolymer (SAN) 1˜5 wt %; chlorinated polyethylene (CPE) 1˜5 wt %; rice husk powder 10˜40 wt %; inorganic filler 10˜40 wt %; internal lubricant 0.1˜1 wt %; external lubricant 0.1˜1 wt %, and heat stabilizer 1˜5 wt %. The VC/VAC copolymer in the husk plastic composition provided by the present invention can allow the composition to be processed by relatively lower processing temperature to save energy consumption. It will also prevent the husk powder from being burnt or decomposed due to high temperature during the heating process to allow this natural material being added in a large amount in the composition. The present invention can reduce the amount of PVC through a large amount of filling additives but still maintain in good product mechanical properties. The particle size of the husk is preferably in the range of 0.10˜0.60 mm for better hardness, stiffness and wood-like texture in the final product.

    摘要: Pressure-sensitive adhesives, adhesive tapes, and methods enable high bond strengths on non-polar or rough substrates. The pressure-sensitive adhesives and methods comprise (a) at least one poly(meth)acrylate, (b) at least one resin A selected from colophony resins and terpene-phenolic resins, (c) at least one hydrocarbon resin B1 having a softening point of greater than 50° C., and (d) at least one hydrocarbon resin B2 having a softening point of less than or equal to 25° C. The adhesive tapes comprise one or more layers of the pressure-sensitive adhesives, and the methods may produce adhesive bonds on substrates with low surface energy and/or on substrates with a mean roughness of at least 5 μm.

    摘要: A polyvinyl alcohol is produced in a method comprising: a polymerization step comprising polymerizing vinyl ester monomers by controlled radical polymerization in the presence of a radical initiator and an organic cobalt complex to obtain a polymer solution containing a polyvinyl ester; an extraction step comprising extracting a cobalt complex from the polymer solution by contacting an aqueous solution containing a water-soluble ligand with the polymer solution; and a saponification step comprising saponifying the polyvinyl ester after the extraction step to obtain a polyvinyl alcohol. A method for producing a polyvinyl alcohol is thus provided that has a narrow molecular weight distribution and a high number-average molecular weight with good hue and further good solubility in water.

    摘要: A process for the preparation of an aqueous polymer emulsion, in which an aqueous emulsion of a polymer which contains at least one chemically bonded monomer having at least one ethylenically unsaturated group is produced in a manner known per se so that the total content of free monomers having at least one ethylenically unsaturated double bond, ie. monomers of this type which are not chemically bonded, in the aqueous polymer emulsion is from >0 to .ltoreq.1% by weight, based on the polymer content of the aqueous polymer emulsion, and this residual monomer content is then reduced by the action of a free radical redox initiator system comprising at least one oxidizing agent and at least one reducing agent, wherein the redox initiator system comprises, as the reducing agent, one which is present, in aqueous solution, in at least two tautomeric forms in equilibrium with one another (for example aminoiminomethanesulfinic acid and/or the salts thereof).
