The dissolution of four sterically hindered amines with molecular weights from 1364 to 2758 was studied in polypropylene in the interval, 60 -130Β°C. The solubility of the additives at 100Β°C passes through a maximum during time and the maximum solubility increases with increasing additive molecular w
## Abstract Polypropylene (PP)βtype resins with narrow molecular weight distribution, such as PPβtype thermoplastic elastomer PER and controlledβrheology PP (CRPP) made by peroxide degradation of high molecular weight PP, have a problem of easy generation of skin roughness at extrusion. To examine
