摘要： A wet laid paper in which at least 1% by weight of the fibrous constituents are UF fibres made from an inorganic oxyacid radical modified UF resin. The inorganic oxyacid radicals are sulphite, phosphate, phosphite, or borate radicals and are present in such an amount that the UF fibres contain 0.2-15 inorganic oxyacid radicals per 100 methylene units. The modified resin is made by reacting urea with formaldehyde in the presence of a source of the oxyacid radicals.

摘要： The invention is a process for making porous amine/aldehyde structures or powders comprising solid approximately-spherical cross-linked particles of less than 10 microns, said process comprising electrolyzing aqueous solutions of urea-formaldehyde prepolymer, melamine-formaldehyde prepolymer or mixtures thereof under electrolysis conditions sufficient to initiate condensation polymerization and formation of said structures or powders. The structures are all broadly designated as open pore urea-formaldehyde structures (OPUF) even though, of course, the ones made from melamine and formaldehyde without urea will have no urea in them. If the reactor is stirred during polymerization powders consisting of primary spherical particles and small porous agglomerates, are formed.

C. The methylation-condensation reaction which follows is carried out at a pH of 5 to 6, preferably 5.4 to 5.7 until a viscosity is obtained which has a minimum of seventeen seconds measured at 20.degree. C. by an AFNOR No. 6 consistometric head. The methylation reaction is then terminated by the addition of aqueous formaldehyde and condensation is carried out for thirty minutes to two hours at 60.degree. to 90.degree.

摘要： A method of making molding compounds, and particularly sheet molding compounds, wherein the reactive monomers are mixed directly with high density inorganic fillers and other ingredients of a molding compound. The monomers are converted to a resin insitu that is in or approaching the B-stage, so that the material is handleable as a solid and is moldable. Because of the amount, type, and thermal conductivity of the fillers, the resinification can be done quickly in a continuous process, by reason of the fact that the monomers are spread over a large surface area of inert fillers to provide good heat transfer, and exceedingly good process control.

摘要： A process is disclosed for performing encapsulation, en masse, by an in situ polymerization reaction to yield capsule wall material. The polymerization comprises a reaction between melamine and formaldehyde and/or polycondensation of monomeric methylol melamine or etherified methylol melamine, or a low molecular weight polymer thereof, in an aqueous vehicle and the reaction is conducted in the presence of negatively-charged, carboxyl-substituted, linear aliphatic hydrocarbon polyelectrolyte material dissolved in the vehicle. Liquid-liquid phase separation is accomplished and maintained by increase in the molecular weight of the resulting condensation polymer without further dilution of the manufacturing vehicle. The negatively-charged polyelectrolyte material is required and has an apparent effect of controlling or modifying the polymerization reaction. The disclosed encapsulation process permits manufacture of micro-capsules in concentrations of capsule to capsule manufacturing vehicle higher than previously possible.
