| titleOfInvention | Production of stereoregular polystyrene |
| abstract | PURPOSE: To easily produce a syndiotactic polystyrene having high stereo- regularity, by using a catalyst comprising a specific almoxane and a specific Ti compound having cyclopentadienyl group. n CONSTITUTION: A stereoregular polystyrene is produced by using a catalyst composed of (A) a Ti compound containing cyclopentadienyl group and expressed by formula Cp 2 TiX 2 (Cp is cyclopentadienyl; X is halogen) [e.g. bis(cyclopentadienyl)titanium dichloride) and (B) one or more almoxanes of formula I and II (R is methyl or ethyl; 1≤n≤40). The almoxane of formula I and II can be produced preferably by slowly hydrolyzing a trialkylaluminum with crystallization water of copper sulfate hydrate, aluminum sulfate hydrate, etc. n COPYRIGHT: (C)1988,JPO&Japio |
