Sascha Schierz,Jan-Hendrik Stockmannions are colored and films cast from them possess ordered structures. In a previous publication (l) ordered structures from clear and colored styrene-butadiene block copolymer films were discussed. The purpose of this investigation was to show, by electron microscopy, the alteration in copolymer str

These are named as “Thermoplastics” or “Segmented Elastomers”, because of their characteristic mechanical properties similar with those of the conventional reinforced rubber vulcanizates at service temperature without both crosslinking and filler-modifying processes (1,2). The elast

Vom Andenpakt zur Andengemeinschaftt was heightened by the possibility that block copolymers might be materials possessing desirable properties, a possibility originally considered by Mark(2). One important class of block copolymers are the polystyrene-polybutadiene-polystyrene block copolymers (S-B-S) introduced by the Shell Chemica

It has been found that the properties of these materials undergo profound alterations when the carboxylic acid groups are neutralized to form various salts. In particular, the optical clarity, tensile strength, impact resistance and melt viscos
