Abstract: A process for the prodn. of reusable fibre composite materials (FCM) contg. fibres (I) bonded together with a polymeric binder is claimed. The binder consists of an aq. dispersion of a polymer (II) which is film-forming at usage temps. and which goes entirely into soln. when the pH of the dispersion medium is changed. Also claimed is (i) material (FCM) obtd. by this process, esp. in the form of non-woven fabric or paper, and (ii) a process for recycling FCM, in which the FCM is treated with an aq. medium at a pH such that polymer (II) is dissolved to give fibres and binder soln., which are then sepd. and reused.

Abstract: Bei einem Verfahren zur Herstellung wiederverwertbarer Faserverbundwerkstoffe, bei dem Fasern mittels eines polymeren Bindemittels miteinander verbunden werden, wird als Bindemittel eine wäßrige Polymerisatdispersion eingesetzt, die einen bei Anwendungstemperatur filmbildenden Polymerisatanteil in disperser Verteilung mit der Maßgabe enthält, daß die Gesamtmenge des in der wäßrigen Polymerisatdispersion in disperser Verteilung enthaltenen, bei Anwendungstemperatur filmbildenden Polymerisatanteils bei pH-Änderung des wäßrigen Dispergiermediums in eine wäßrige Polymerisatlösung übergeht. Dabei kann der bei Anwendungstemperatur filmbildende Polymerisatanteil der wäßrigen Polymerisatdispersion protische Säuregruppen aufweisen, und seine disperse Verteilung im wäßrigen Medium kann durch Erhöhung des pH-Werts des wäßrigen Mediums in eine wäßrige Polymerisatlösung übergehen, oder er kann basische Gruppen aufweisen, insbesondere Aminogruppen, und seine disperse Verteilung kann im wäßrigen Medium durch Absenkung des pH-Werts des wäßrigen Mediums in eine wäßrige Polymerisatlösung übergehen.

Abstract: The present invention relates to the use of active coal for reducing odor emissions from aqueous polymer dispersions and products obtained therefrom. It also pertains to aqueous polymer dispersions containing 0.1 to 20 wt.% of active coal, their use as a binder for fibre composites, and the fibre composites themselves.

The binder consists of an aq. dispersion of a polymer (II) which is film-forming at usage temps. and which goes entirely into soln. when the pH of the dispersion medium is changed. Also claimed is (i) material (FCM) obtd. by this process, esp. in the form of non-woven fabric or paper, and (ii) a process for recycling FCM, in which the FCM is treated with an aq. medium at a pH such that polymer (II) is dissolved to give fibres and binder soln., which are then sepd. and reused.
