TL;DR: In this article, cold-set adhesives are described, which are liquid at a temperature of 60°C. or more, but lose their fluidity to gelatinize on cooling at higher than 20°C, and are very useful for a cold corrugation system.
Abstract: Adhesives prepared by dissolving polyvinyl alcohol, a filler and a water-soluble boron compound in water are described. These adhesives are "cold-set" adhesives which are liquid at a temperature of 60° C. or more, but lose their fluidity to gelatinize on cooling at a temperature higher than 20° C., they are very useful for a cold corrugation system.
TL;DR: A waterproof wood glue showing little discoloration, which is based on an aqueous 30-65 wt.% polyvinyl ester (I) dispersion stabilised with PVA, contains 0.5-7.0 mPa s as discussed by the authors.
Abstract: A waterproof wood glue showing little discoloration, which is based on an aqueous 30-65 wt.% polyvinyl ester (I) dispersion stabilised with polyvinyl alcohol, contains 0.5-7.5 wt.% polyvinyl alcohol(s) (PVA; w.r.t. the dispersion) with a Hoeppler viscosity of 2.0-6.0 mPa s (measured in 4% aqueous solution). Also claimed is a method of producing the adhesive.
TL;DR: A gooey, stretchy, cross-linked polymer similar to "slime" produced by cross-linking polyvinyl alcohol and to commercially available Gak and Silly Putty is described in many science activity resources.
Abstract: The procedure presented here was adapted from an activity published by the Institute for Chemical Education. It is described in many science activity resources- some intended for young children. The product in the reaction is a gooey, stretchy, cross-linked polymer similar to "slime" produced by cross-linking polyvinyl alcohol and to commercially available Gak and Silly Putty. The activity can be done in the chemistry laboratory or at home. If done at home, the instructor may need to provide borax powder or solution. Students may both enjoy and benefit from doing this activity outside of class with a younger student.
