ABSTRACT:
A copolymer of vinyl chloride with ethylene or propylene having a K-value of 45 to 65 and an alkylene (ethylene or propylene) content of 0.5 to 10 weight percent. This product is particularly useful for forming plasticizer-free coatings on substrates by known fluidized bed coating processes and for forming plastizer-free shaped articles by rotational molding processes.
