<p>The moulding cmpd. comprises 70 to 99 pbw of a vinyl chloride (co)polymer and 1 to 30 pbw of an epichlorohydrin-ethylene copolymer contg. 30 to 80 wt.% units derived from epichlorohydrin. It has excellent mechanical strength, processability and weathering resistance, even gelling, low softening temp. and sufficient flowability at low temp. Used for prodn. of mouldings having high heat resistance, weatherability transparency and impact strength.</p> |
