摘要： An expandable blend of a linear olefinic polymer and a cross-linkable polymer for production of lightly cross-linked foamed polymers and a process for the preparation thereof is provided. The presence of a cross-linkable polymer component in the blend increases the melt strength of the linear olefinic component so that conventional melt processing techniques may be utilized to produce foamed polymers. Both open and closed-cell foams may be produced.

摘要： Promoters for a crosslinking reaction involved in the curing of a system comprising crosslinkable polymers are bound to polymeric microparticles having a diameter of about 0.01 to 6 microns prepared by polymerizing a mixture of ethylenically unsaturated monomers. The microparticles carrying the crosslinking reaction promoter may be incorporated to coating compositions, printing inks, sealants, adhesives and other polymeric products in place of conventional crosslinking reaction promoters.

摘要： Polyorganosiloxanes that are curable to crosslinked solid material, at ambient temperature upon exposure to gaseous oxygen, wherein the polyorganosiloxane contains, per molecule, at least one monovalent olefinically polyunsaturated organic radical containing at least one 1,3-pentadienylene group or 1,4-pentadienylene group bonded to silicon through silicon-to-carbon bond and wherein any remaining valence of silicon is satisfied by a silicon-to-oxygen-to-silicon bond or by a monovalent organic radical free or more than one olefinically unsaturated group per monovalent organic radical, which monovalent organic radical is bonded to silicon by a silicon-to-carbon bond. Compositions are also described containing the novel polyorganosiloxanes, suitable driers either chemically combined in the polyorganosiloxane or physically mixed therewith. The compositions can also contain fillers, plasticizers and/or catalyst activators.

摘要： Poly(ethylene terephthalate) resin and blends of poly(ethylene terephthalate) resin with other polymers are extruded while being coupled with an organic diisocyanate under conditions where carbon dioxide gas is vented smoothly, as it is formed. The extruder has a number of zones (1) to (6) designed to perform specific functions. The temperature in the kneading zone (4) and in the venting zone (5) must be maintained at about 280-320°C to bring about rapid reaction and to permit efficient gas evolution and removal without thermally degrading the polymeric material. The extruded article is free of trapped gas bubbles and other imperfections. This process is particularly suitable for making PET billets, which then are stretched to form strapping useful in packaging applications.

摘要： This invention relates to a polyvinyl chloride sheet, at least one surface of which is crosslinked. The thickness of the crosslinked layer is between 0.05 and 2µm, the degree of chlorination is not greater than 45% compared to the non-crosslinked sheet, and the degree of heat shrinkage is not greater than 1 %. This sheet is particularly suitable for use in the manufacture of blood bags and infusion bags.
