Title
(EN) BIODEGRADABLE HOT MELT ADHESIVES
(FR) ADHÉSIFS THERMOFUSIBLES BIODÉGRADABLES
Abstract
(EN)
The present disclosure provides a hot melt adhesive which includes at least the following components: (1) from about 10 to about 20 weight percent of a lactic acid oligomer or polymer having a weight average molecular weight from about 1500 to about 3000; (2) from about 40 to about 75 weight percent of polylactide having a weight average molecular weight from about 10,000 to about 18,000; (3) from about 20 to about 35 weight percent of a polyester formed from the copolymerization of one or more diols and one or more dicarboxylic acids; and (4) from about 0.5 to about 5 weight percent of a copolymer of vinyl acetate and a mono-unsaturated short chain fatty acid, the fatty acid having from 4 to 12 carbon atoms. All of the aforementioned weight percentages are based on the overall weight of the hot melt adhesive. An adhesive-coated substrate and a method for applying a hot melt adhesive to a substrate are also disclosed.

La présente invention concerne un adhésif thermofusible qui comprend au moins les composants suivants : (1) d'environ 10 à environ 20 pour cent en poids d'un oligomère ou polymère d'acide lactique possédant un poids moléculaire moyen en poids d'environ 1.500 à environ 3.000; (2) d'environ 40 à environ 75 pour cent en poids de polylactide possédant un poids moléculaire moyen en poids d'environ 10.000 à environ 18.000; (3) d'environ 20 à environ 35 pour cent en poids d'un polyester formé à partir de la copolymérisation d'au moins un diol et d'au moins un acide dicarboxylique; et (4) d'environ 0,5 à environ 5 pour cent en poids d'un copolymère d'acétate de vinyle et d'un acide gras à chaîne courte mono-insaturé, cet acide gras possédant 4 à 12 atomes de carbone. Tous les pourcentages en poids susmentionnés sont basés sur le poids total de l'adhésif thermofusible. L'invention concerne également un substrat revêtu d'adhésif, ainsi qu'un procédé d'application d'un adhésif thermofusible sur un substrat.
