The information in the text is summarized as follows:
Novel oligo- and polyenaminones with Mw-3000 Da were prepared in excellent yields by amino-enaminone ‘click’ polymerization of 1,3- and 1,4-bis[3-(dimethylamino)acryloyl]arenes with 1,3- and 1,4-phenylenediamine. The obtained oligomers and polymers were depolymerized quant. to the starting bis-enaminones and diamines by treatment with excess dimethylamine in ethanol at 50°C. This simple polymerization/depolymerization method allows for a closed-loop recycling of polyenaminone-based materials. UV light absorbance at wavelengths below 470 nm indicates promising optical properties of these polymers.

N,N-Dimethylformamide Dimethyl Acetal(cas: 4637-24-5) belongs to anime. In organic chemistry, amines are compounds and functional groups that contain a basic nitrogen atom with a lone pair. Amines are formally derivatives of ammonia (NH3), wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group (these may respectively be called alkylamines and arylamines; amines in which both types of substituent are attached to one nitrogen atom may be called alkylarylamines).Related Products of 4637-24-5
