Remarkable examples are blends of isotactic or syndiotactic
poly(styrene) with polyfvinyl methyl ether) [58-60], polyfvinylidene fluoride) with poly(1,4-butylene adipate) , and PLA with polyethylene oxide) .
Respectively, the matrials are: (1) the first "all bio" polylactic acid (PLA) and polybutylene succinate (PBS) formulations for durable injection-molded parts, (2) a new syndiotactic
elastomer for calendering, and (3) an amorphous metal that can be molded using injection molding machinery.
The major driver for developing and introducing (post-)metallocene catalysts in the polyolefin industry has been product differentiation, resulting in, among others, syndiotactic
polypropylene, homogeneous linear, low density polyethylene and copolymers of ethylene with higher a-olefins (plastomers).
Mitsui Chemicals Launches New Notiosn Syndiotactic
Idemitsu Kosan to raise price of syndiotactic

Polystyrene for Model Semicrystalline Ionomer Investigations.
polystyrene; synthesis, characterization, processing, and applications.
One recent bad example of not learning the customer's key functional requirements, and of not determining competitive cost-performance models early, involved a new high-temperature crystalline engineering thermoplastic, targeted in large part at automotive applications (Questra[R] syndiotactic
Our simulation results show that it is the syndiotactic
sequences along the backbone of aPP that cause the formation of such nano-scaled structures.
A recent ABB fusebox application used a syndiotactic
polystyrene (SPS) to replace the older thermoset model, resulting in more than a 20% cost reduction.
