摘要： A method of establishing an essentially steady state cross-flow filtration flow in a cross-flow membrane filtration module by starting at a low transmembrane pressure (TMP) and steady state operation and then increasing the TMP by an iterative procedure until the performance starts to become unstable and then backing down the TMP slightly until the performance restabilizes. One preferred embodiment employs a filtration module that describes a flow length such that the permeate pressure is equal to the concentrate pressure.

摘要： Polyurethane foam backed textiles, particularly polyurethane backed carpets can be prepared using a formulation including a dialkyltin sulfide catalyst. Use of the dialkyltin sulfide catalyst allows for a delayed gellation without substantially increasing the time from gellation to cure. The delay in gellation provides for improved handling and backing quality.

摘要： Radial block copolymers characterized by the formulas: (1) (pS-pI)nX and (2) (pS-pI-pB)nX where pS is polystyrene, pI is polyisoprene, pB is butadiene, X is a residue of a multifunctional coupling agent used in the production of the radial block copolymer, and n is a number greater than 2 representative of the number of branches appended to X; hot-melt adhesive compositions constituted of said radial block copolymers, and articles of manufacture produced therefrom. These copolymers possess blocks of high average molecular weight polystyrene (10,000 to 25,000) and an overall average molecular weight (90,000 to 380,000) such that when blended in requisite proportions with a compatible tackifier resin, preferably also a secondary tackifying resin or plasticizing oil, and stabilizer, superior hot-melt adhesive compositions can be formed. The hot-melt adhesive compositions possess, inter alia, superior heat resistance, superior static time to failure with low viscosity, good peel adhesion, good tack, and high ability to bond to a polyethylene or polypropylene substrate at temperatures below that which may damage the substrate.

摘要： A method of preparing epoxy parts wherein the interval of low viscosity of an amine-hardened epoxy system can be extended without sacrifice of cure time. Suitable catalysts for the epoxy-amine hardener reaction are generated in situ. As an advantage, more epoxy articles may be prepared with a given mold capacity having improved wet-out of fiber reinforcement attributed to a larger interval of low viscosity.

摘要： A polystyrene foam sheet comprising a polystyrene resin which contains 1 to 15 wt. % of a rubber component having a majority of particle sizes less than about 0.45 microns has been found to be superior for forming deep drawn articles. Optionally one or two films may be extrusion coated or laminated to the foam sheet prior to thermoforming. Also disclosed is a method for thermoforming the foam sheet. Preheat the sheet, clamp the sheet between the matched male (10) and female (50) mold members, move the members into final position while applying a vacuum through both members to both sides of the foamed sheet and then chill formed foam to set a final shape.
