Title (EN) HOT MELT PROCESSABLE PRESSURE SENSITIVE ADHESIVES CONTAINING FIBROUS MATERIALS
(FR) ADHÉSIFS AUTOCOLLANTS THERMOFUSIBLES
Abstract: front page image
(EN)The methods of preparing hot melt processable pressure sensitive adhesives include combining an elastomeric (meth)acrylate random copolymer and a discontinuous fibrous material in a hot melt mixing apparatus, and mixing to form a hot melt processable pressure sensitive adhesive. The elastomeric (meth)acrylate random copolymer may be contained within a thermoplastic pouch, and the hot melt mixture may include a relatively high level of tackifying resin. The elastomeric (meth)acrylate random copolymer may contain branching agents and photosensitive crosslinking agents. The hot melt processable pressure sensitive adhesives can be used to prepare transfer tapes.
(FR)L'invention concerne des procédés permettant de préparer des adhésifs autocollants thermofusibles consistant à combiner un copolymère aléatoire (méth)acrylate élastomère et un matériau fibreux discontinu dans un appareil de mélange à chaud, puis à mélanger afin de former un autocollant thermofusibles. Le copolymère aléatoire (méth)acrylate élastomère peut être contenu dans un sachet thermoplastique et le mélange thermofusible peut comprendre un niveau relativement élevé de résine donnant du collant. Le copolymère aléatoire (méth)acrylate élastomère peut contenir des agents de ramification et des agents de réticulation photosensibles. Les autocollants thermofusibles peuvent être utilisés pour préparer des bandes de transfert.
