| A series of SBS
and SIS copolymers have been developed for use by
producers and compounders of olefinic and styrenic
thermoplastics, engineering resins, thermosets,
blends, and alloys. VECTOR® styrenic block copolymers
are used as additives to enhance the toughness and
impact strength of these plastics at ambient and
low temperature. Since SBS and SIS are diblock-free,
they also extend the higher temperature performance
range of the modified base resin compared to conventionally
polymerized SBC's that contain diblock residues.
Certain grades have been specially designed for
use as base feedstocks for the manufacture of
more advanced engineering resins, while others
are tailored to overcome the deleterious effects
of additives such as flame retardants. VECTOR
SBC's can be used to enhance compatibility
between dissimilar plastics, creating novel and
unique alloys and blends exhibiting the best
features of both. The superior heat resistance
of halide-free VECTOR SBCs is readily demonstrated in improved
color stability of the base resin, and is especially
evident after multiple-heat exposures of in-plant
recycle.
Recycling of plastics is another focus of
product development activities. For homogeneous
recovered plastics, the addition of VECTOR styrenic
block copolymer can renew properties, resulting
in near-virgin product performance.
