    摘要： The invention pertains to a method for preparing a composite printing form from a single precursor that is capable of forming a relief and a carrier. The single precursor can be a single photosensitive element or a single laser-engravable print element having a reinforced elastomeric layer. The single precursor has a size that is at least 70% of a size of the carrier. The single precursor is located on the carrier by approximately positioning the precursor on the carrier that has no registration markings. Precise registration of the single precursor is achieved by using digital information generated from a computer to create the registered image on the composite form. The method is particularly suited for preparing composite printing forms for relief printing, and in particular for preparing composite printing forms for flexographic printing of corrugated substrates.

    摘要： Provided are methods for obtaining modified polyarylene sulfide compositions having improved thermal and thermo-oxidative stability, the compositions so obtained, and articles comprising the compositions. The method comprises the steps of contacting, in the presence of a suitable solvent, a polyarylene sulfide with at least one reducing agent and at least base to form a first mixture. The reducing agent comprises zinc(0), tin(0), tin(II), bismuth (0), bismuth(III), or a combination thereof. The first mixture is heated to form a second mixture in which the polyarylene sulfide is dissolved. The polyarylene sulfide is then precipitated to obtain a modified polyarylene sulfide.

    摘要： A lubricant component is a copolymer of ethylene and α-olefins made by forming a series of α-olefins by oligomerization of ethylene using an oligomerization catalyst, and then copolymerizing the α-olefins and ethylene using a transition metalcontaining polymerization catalyst. The copolymer, which often has a high Viscosity Index, may be used, for example, in a lubricant as the base oil or a viscosity index modifier. The polyolefin may also be a component of a lubricant additive, meant to be added to an already formulated lubricant to improve the lubricant's properties.
