Title: Improvements in phosphinoborines and their production
Inventor: BURG ANTON BEHME
IPC: C07F9/6596
Filed: 1959-03-24
Abstract: The invention comprises phosphinoborine copolymers of the formula (RR1PBH2)n(R11 PBH)m wherein R, R1 and R11 designate the same or different alkyl, cycloalkyl or aryl groups and n and m are integers, comprising alternatively linked phosphorous and boron atoms arranged in fused rings.  The copolymers are made by heating together a secondary phosphine borine having the formula RR1HP : BH3 and a primary phosphine borine R11 H2P : BH3.  The preferred reaction temperatures are between 170 DEG  and 320 DEG C. which may generally be achieved by refluxing the mixture of phosphine borines in an inert atmosphere in the absence of a solvent.  A high-boiling solvent such as di-n-butyl ether or triethylene glycol dimethyl ether may be used if desired.  The high molecular weight copolymers form glassy products which are resistant to thermal decomposition, oxidation and hydrolysis and find utility as dielectrics.ALSO:The invention comprises phosphinoborine copolymers comprising alternatively linked phosphorus and boron atoms arranged in two or more fused rings, each pair of phosphorus and boron atoms forming the basis of a structural unit having the formula : -(RR1PBH2)- or <(R11PBH)<, R1,R1, and R11 being the same or different alkyl, cycloalkyl or aryl groups, the individual rings being formed of 1 of the >(R11PBH)< and 2 or 3 of the -(RP1PBH2)-units in each terminal ring and 1 or 2 of the -(RR1PBH2)- units and 2 or 3 of the > (R11PBH)< units in each non-terminal ring.  The copolymers are made by heating together a secondary phosphine borine having the formula RP1HP:BH3 and a primary phosphine borine R11H2P:BH3.  The preferred reaction temperatures are between 170 DEG  and 320 DEG C. and the reaction may be effected by refluxing the mixture of phosphine borines in an inert atmosphere in the absence of a solvent.

Title: Moulding polyurethane foam
Inventor: WOOLER ALAN METCALF
IPC: B29C33/40
Filed: 1962-03-20
Abstract: A polyurethane foam is allowed to form in a mould made from foamed plastic material. The would may have a lid and may be made either by coating a plaster cast with a release agent and then applying the foam or by sticking sheets or slabs of foamed material into a box shape.  The process may be carried out continuously by allowing the foam to form on a moving conveyer between guides which are moving in the same direction, the conveyer and the guides being covered with foamed material. A stationary or moving cover may be furnished above the guides and a foamed plastic end curtain may be used.  The foamed plastic material may be urea-formaldehyde or phenolformaldehyde resin or may be a rigid polyurethane foam produced from an organic polyisocyanate and a hydroxyl-group containing polymer in the presence of a low boiling organic liquid, e.g. a fluorinated hydrocarbon. The mould may be lined with a release agent, e.g. a silicone fluid or resin, a mineral or vegetable oil, a grease, wax or polytetrafluoroethylene, or a thin film of paper or polyethylene or for permanent adherance fabric, leather, fur or felt.  The moulded polyurethane may be flexible, rigid or semi-rigid and may be prepared from an organic polyisocyanate and a hydroxyl-group containing polyester, polyesteramide or polyether with added water and/or low boiling point organic liquid.  In the example a polyether prepared from propylene oxide and glycerol is reacted with tolylene diisocyanate and water in the presence of stannous octoate, triethylene diamine and a siloxane/oxyalkylene block copolymer. Foaming takes place in a closed mould made from polyurethane slabs and lined with a polythene bag.

The process of the parent Specification (wherein a blend of a molten filament-forming synthetic thermoplastic polymer and a minor proportion of a blowing agent which at the extrusion temperature is itself or evolves, a gas is extruded in film form, the film is drawn as it leaves the extrusion die and the drawing is continued while the film is maintained at a temperature above the glass transition temperature of the polymer until fibrillation occurs and the fibrillated film is solidified) is modified in that the blend is subdivided as it is extruded, so that it issues from the extruder as a plurality of ribbons, each of which has a width to thickness ratio of from 200 : 1 to 20,000 : 1, and the ribbons are simultaneously drawn to fibrillation, and solidified. The subdivision of the melt as it is extruded can be effected by using an extrusion die provided with dividers which can be fixed, e.g. formed integrally with the die lips, or adjustably mounted within or against the die lips. The die itself can be a slot die such as would normally extrude a flat film or a die provided with an annular outlet such as would normally produce a tubular film. In an example, a mixture of a polypropylene having a melt index of 6À5 and an inherent viscosity of 2À2 in decalin at 135‹ C. and 1% of azodicarbonamide is melt extruded through a die-head maintained at 240‹ C. and having a slot type extrusion orifice 6 inches long and 0À020 inch wide, the slot being provided with polymer stream dividers 1¢ inches apart. The extruded ribbons are cooled at a controlled rate to below their softening temperature by means of jets of air at 20‹ C. and 90 p.s.i.g. pressure directed into the upper and lower surfaces of the ribbons by means of quench tubes. The solidified ribbons are passed over a driven first roll whereby a fibrillated product is obtained which is then drawn by passage over a shoe maintained at 125‹ C. followed by a second roll driven at three times the peripheral speed of the first roll.
