Abstract
Procedeu de fabricare a policlorurii de vinil-suspensie, conform inventiei, consta în polimerizarea clorurii de vinil în suspensie în prezenta unor concentratii relativ mari de oxigen în amestecul de polimerizare (presiuni remanente înainte de încarcarea monomerului de 350 ... 500 mm Hg). în scopul mentinerii stabilitatii termice a polimerului rezultat în amestecul de polimerizare, se introduce 0,01 ... 0,03 % 1.1,1 - trimetilpropan fata de clorura de vinil. Pe lânga mentinerea calitatii polimerului obtinut prin aplicarea procedeului, se pot realiza însemnate economii energetice si materiale.
