An epihalohydrine (co)polymer, e.g. an epichlorohydrin-THF copolymer, is reacted with an alkali metal cpd. of cyclopentadiene, e.G. cyclopentadienyl - Na, to form a polyether with pendant cyclopentadiene rings, and the prod. is cross - linked by heating to <=150 degrees C. Easily shapable moulding cpds. are obtd. suitable for mfr. of mouldings having good thermal, dimensional and chemical stability. |
