摘要： Provided is a continuous process for converting waste plastic into recycle for polyethylene polymerization or for normal alpha olefins. The process comprises selecting waste plastics containing polyethylene and/or polypropylene and then passing the waste plastics through a pyrolysis reactor to thermally crack at least a portion of the polyolefin waste and produce a pyrolyzed effluent. The pyrolyzed effluent is separated into offgas, a naphtha/diesel fraction, a heavy fraction, and char. The naphtha/diesel fraction is passed to a crude unit in a refinery from which is recovered a straight run naphtha fraction (C5-C8) or a propane/butane (C3-C4) fraction. The straight run naphtha fraction, or propane and butane (C3-C4) fraction, is passed to a steam cracker for ethylene production. The ethylene is converted to normal alpha olefin and/or polyethylene. Also, a heavy fraction from the pyrolysis reactor can be combined with a heavy fraction of normal alpha olefin stream recovered from the steam cracker. The combined heavy fraction and heavy fraction of normal alpha olefin stream can be passed to a wax hydrogenation zone to produce wax.

摘要： A water-based acrylic pressure-sensitive adhesive for clothing and a preparation method thereof are provided. Since a specific internal crosslinking agent is used in a predetermined range during polymerization of an acrylic emulsion resin, a glass transition temperature and an internal crosslinking degree may be controlled while maintaining physical properties of the resin equal to those of the existing adhesives, and thus a residual ratio of the pressure-sensitive adhesive may be greatly reduced at the time of removing the pressure-sensitive adhesive from a substrate such as a fabric for clothing, etc.

摘要： Compositions are disclosed which include between about 0.05 to about 5 or less wt. % of at least one acrylate monomer based on the total weight of the composition. The acrylate monomer reduces the peak cure temperature, thereby accelerating the rate of cure, without sacrificing completeness of the cure or the release performance of the cured product. The addition of the acrylate monomer also enables a reduction in the amount of costly platinum catalyst required to effectively cure a composition. In addition to the acrylate monomer, the compositions also include a silicone base polymer, a crosslinking agent, and platinum catalyst. The cured compositions exhibit properties useful for incorporation into release liners, adhesive articles, medical products and gaskets.

摘要： Metallocene complexes represented by the structure below are useful for alpha olefin oligomerization in the presence of an activator to generate polyalphaolefins having a high percentage of vinylidene termination and relatively low Mn values. M is a group 4 transition metal. A is a bridging group having one bridging atom extending between a first indenyl ring and a second indenyl ring. Each X is independently an anionic ligand, or two Xs are joined and bound to M to form a metallocycle ring, or two Xs are joined to form a chelating ligand, a diene ligand, or an alkylidene ligand. R1, R1′, R3, R3′, R4, R4′, R7 and R7′ are hydrogen. R5, R5′, R6, and R6′ are independently a C1-C10, optionally substituted, hydrocarbyl group, or R5 and R6 and/or R5′ and R6′ are bonded together to form an optionally substituted hydrocarbyl ring structure.

摘要： A conventional polymerization inhibitor is for example an agent to scavenge radicals generated during storage of a radical polymerizable compound and used to stably handle the radical polymerizable compound, but is unnecessary when the radical polymerizable compound is to be subjected to radical polymerization reaction, and is preferably removed at the time of the radical polymerization reaction. The object of the present invention is to obviate inconvenience of removing the polymerization inhibitor at the time of radical polymerization.
The radical polymerization control agent contained in a radical polymerizable composition of the present invention functions as a radical polymerization inhibitor for example stored in a dark place, but loses its radical polymerization inhibiting effect when polymerization is initiated while being irradiated with light at a certain specific wavelength at the time of polymerization. Thus, radical polymerization of the radical polymerizable compound is easily initiated without increasing the amount of a radical polymerization initiator. That is, the radical polymerization control agent of the present invention is a radical polymerization control agent which is a corn pound having an effect to inhibit radical polymerization of a radical polymerizable compound and which loses the radical polymerization inhibiting effect under irradiation with light rays containing light within a wavelength range of from 300 nm to 500 nm.
