TLDR
Mixtures of two distinct polyvinyl butyral grades, viz., one high viscosity and one low-viscosity grade, both having a narrow molecular weight distribution exhibit good processing characteristics which nearly reach the performance of the high-viscosity grades hitherto used as discussed by the authors.Abstract:

Interlayer for laminated glass, and laminated glass
Minoru Nakajima,Isei Sannomiya +1 more
TL;DR: An interlayer for laminated glasses which does not cause the moire phenomenon even when having an embossed pattern with grooves and ridges disposed regularly or arranged at a regular interval, hence has satisfactory workability in cutting or laminating, and is highly effective in expelling air in preliminary press bonding as mentioned in this paper.
Patent
Interlayer film for a laminated glass
TL;DR: An interlayer film for laminated glass comprising laminated layers of at least one layer (A) which comprises a plasticizer and polyvinyl acetal resin for which the number of carbon atoms in the acetal group is 4, 5 or 6 and the mole ratio of the average amount of the ethylene groups bonded to acetyl groups is 8-30 mole % of the total amount of main chain EGs.

Interlayers for use in sound-insulating laminated glasses
TL;DR: An interlayer for sound-insulating laminated glasses which is in the form of a laminated film of two kinds of resin films (A and B) was proposed in this article.
Patent
Multiple Layer Polymer Interlayers Having a Melt-Fractured Surface
TL;DR: In this paper, the surface topography of the interlayer is controlled by controlling the melt fracture that occurs at the exposed surface of interlayer or individual layers of the multiple layer interlayer during formation.
Patent
Polyvinyl acetal resins based on hydroxyaldehydes and use of the resins in laminar structures
TL;DR: In this paper, a process for making polyvinyl acetal resins based on 4-hydroxybutanal is described, and laminar structures that include the resins, a process to make the resin, and a process of making an internally plasticized PU-acetal resin by esterification are revealed.

Process for producing polyvinyl acetal
TL;DR: In this paper, a process for preparing polyvinyl acetals was described, where the reaction system was maintained at a temperature of not more than 20*C. and the reaction was continued at this temperature.
Patent
Stabilized polyvinyl butyral and stabilizer for polyvinyl butyral
TL;DR: Stabilized polyvinyl butyral as discussed by the authors is obtained by incorporating a usual phenolic stabilizer together with a phosphorous acid triester, the composition containing from about 0.6 to 4.5 % by weight of the sum of the phenolic stabilization and the acid based on the resin.
Patent
Stabilized polyvinyl acetal interlayers
TL;DR: In this paper, a mix-ture of 2,6-DI-N-OCTADECYL-P-CRESOL STABILIZERS and an ALKYLATED HYDROXY PHENYL BENZOTRIAZOLE is described.
