Title: Manufacture of polyvinyl acetal resins
IPC: C08F8/28
Filed: 1945-08-03
Abstract: Polyvinyl acetal resins having 9-30 per cent residual polyvinyl alcohol are made by adding with vigorous agitation one or more aldehydes containing at least two carbon atoms to a preponderantly aqueous solution of a polyvinyl ester hydrolysed to at least 75 per cent, containing all of the hydrolysed ester to be reacted, in presence of an acid catalyst and absence of a dispersing agent, other than a colloid capable of being converted into the acetal being produced, at below 45 DEG  C., continuing agitation while a partially acetalized resin is precipitated, and then maintaining or raising the temperature while continuing agitation until the desired composition of product is obtained. The hydrolysis of the polyvinyl ester may be carried out in presence of an acid catalyst, preferably the same as that used in the acetalization, and is preferably effected within the range 40 DEG  to 70 DEG  C.  Acid corresponding to the polyvinyl ester used may be added to the dispersion before or with the acid catalyst.  The hydrolysis of the polyvinyl ester may be carried out continuously by hydrolysing in presence of an acid catalyst to an intermediate stage, replacing part of the solution by further polyvinyl ester dispersion and acid catalyst, repeating the cycle of operations, diluting successive portions of solution removed with water and permitting hydrolysis to proceed to at least 75 per cent, using the same acid catalyst as used in the acetalization.  The polyvinyl ester dispersion used may be in the form of beads, flakes or powder of polymer, dispersed in water or produced by polymerization of the monomer in aqueous emulsion.  If desired, the acetalized product may be washed with water and then at elevated temperatures, e.g. 70-95 DEG  C., with aqueous sodium or potassium hydroxide.  Specified aldehydes are acetaldehyde, paraldehyde, butyraldehyde, propionaldehyde and benzaldehyde. Polyvinyl acetate is the preferred ester.  Specification 577,861 is referred to.

Abstract: 480,356. Luminescent materials. GENERAL ELECTRIC CO., Ltd., McKEAG, A. H., and RANDALL, J. T. July 23, 1936, Nos. 20445/36, 34284/36, 5694/37, and 12704/37. [Class 98 (i)] Means for producing light comprises in combination a source of radiation which in operation emits the mercury spectrum and luminescent material exposed to the radiation wherein the material is activated zinc-beryllium silicate with or without other luminescent materials. The preferred composition of material is ZnO.BeO.Si02 activated with manganese, the colour of the emitted light varying with the proportion of the activator. The material may be prepared by mixing powdered beryllium oxide, zinc oxide, and silica with water to a stiff paste and adding sufficient MnCl2 to give À5 per cent Mn in the final product. The mixture is then heated in a silica boat to 1250‹ C. for 3 to 4 hours, ground, and sieved to the desired particle size. With a higher proportion of manganese a lower temperature is used, e.g. with 1À5 per cent Mn, a temperature of 1150‹ C. The material may be used with high or low pressure mercury vapour lamps. For example, a cold electrode tube with a mercury-argon filling gives a white light when the material is distributed on the inner surface of the envelope, a current density of 5-50mA /cm<2> being used. To increase the proportion of red light in the emission cadmium silicate activated with manganese may be included in the mixture. Specifications 431,409, [Group XL], and 478,302 are referred to.
