Thermal stability of hyperbranched polyglycerols esterified with dicarboxylic acid and phthalic anhydride applicable as hot melt adhesives. Thermal stability of three hot melt adhesives was investigated by means of TGA. It was shown that hyperbranched polyglycerols esterified with phthalic anhydride or sebacic acid exhibited excellent thermal stability. 50%-mass loss was observed above 400ºC in all cases, however the higher temperatures of final degradation were found for the formulations containing phthalate units.

Quebracho tannin - hyperbranched polyglycerolblends as adhesives for wood bonding.Applicability of tannin-hyperbranched polyglycerol blends cured with hexamine in wood bonding was investigated. Adhesive performance of the systems was examined. It was shown that strengths of adhesive joints exceeded that of the substrate, therefore it was concluded that hyperbranched polyglycerols might be effective components of tannic adhesives.

EN
Performance of polyurethane wood adhesives based on hyperbranched polyol bearing glucose core. In this paper synthesis of a hyperbranched polyglycerol containing glucose core and terminal hydroxyl functionalities as well as its application as a component of polyurethane adhesives were described. It was shown that an addition of long-chain components to the formulation was necessary for improved shear strength of the joints, since neat polyglycerol provided brittleness of the cured polyurethane.

Hyperbranched polyglycerol esters as hot melt adhesives. Four esterified hyperbranched polyglycerols of different structure and functionality (hydroxylated or partially carbonated) were used as polyol components of hot melt adhesives. It was shown that properly formulated polyester might exhibit performance comparable to that of a commercial hot melt.

EN
Effect of hydroxyl functionality of branched polyol component on PUR curing thermal effect. Three hyperbranched polyglycerols of different structure and functionality were used as polyol components of polyurethane wood adhesives. Thermal effect of cross-linking with PMDI was investigated by means of DSC. It was shown that thermal effect was more affected by hydroxyl functionality than by benzyl substituents that remain inert upon curing.
