Tributyl thiourea

Compression set resistance can be improved considerably in all types of polychloroprene by effecting a very tight cure. Thus, long cure times, high curing temperatures and high accelerator concentrations are beneficial. While acceleration with ethylene thiourea (1 phr) or diethyl thiourea (1 phr) for fast continuous vulcanisation will meet most requirements, for the most demanding specifications it may be necessary to use trimethyl thiourea (2 phr) and epoxy resin (1 phr) or tributyl thiourea (3-4 phr). [Pg.146]

An aromatic halide linked to a polystyrene resin 52 was treated with tributyl(l-ethoxyvinyl)tin under Stille conditions to give a vinyl ether which was treated with NBS to afford the a-bromoketone 53. Subsequent reaction with a thioamide or thiourea gives 2,4-disubstituted or 2-aminothiazoles 54, after cleavage of the resin, in good to excellent yields <02TL3193>. [Pg.238]
