Beschreibung
Zusammenfassung:	According to the present invention there is provided a thermo-chemically cross-linked poly-(p-methylstyrene) having a Vicat softening temperature of at least 99 DEG C. This composition is prepared by incorporating a high temperature initiator in the monomeric p-methylstyrene and polymerizing this, usually in the presence of a conventional polymerization initiator, to produce a cross-linkable poly(p-methylstyrene), which is then cured at elevated temperatures sufficient to activate the high temperature initiator and cross-link the polymer.
