PROCESS FOR THE FLOCCULATION POLYURETHANE ELASTOMER SOLUTIONS IN DIMETHYLFORMAMIDE

Inventia se refera la un procedeu pentru flocularea solutiilor de elastomeri poliuretanici în dimetilformamida provenite din industria pielii sintetice conform caruia solutia de elastomeri se introduce ca agent de floculare poli-(clorura de N,N-dimetilpiperidiniu) în proportie de 0,001...0,5g/l de s...
