Copolymers styrenic block

Styrene-Butadiene-Styrene Block Copolymers. Styrene blocks associate into domains that form hard regions. The midblock, which is normally butadiene, ethylene-butene, or isoprene blocks, forms the soft domains. Polystyrene domains serve as cross-links. [Pg.1024]

Of the amorphous block copolymers, styrenic block copolymers are the vast majority. These are synthesized anionically in solution, with butyl lithium commonly employed as the initiator [4]. There are three processes for this polymerization ... [Pg.713]

Another example is Dias Analytics styrenic membrane based on the well-known block copolymer styrene-ethylene/butylene-styrene family.This membrane has good conductivity 0.07 to 1.0 S/cm when fully hydrated. It showed reasonable performance but had poor oxidative stability due to the susceptibility of its aliphatic backbone to peroxide attack. [Pg.282]

Styrene/isoprene/styrene (SIS) block copolymer (styrene isoprene ratio of 15/80 to 30/70 by weight) is a thermoplastic rubber. This copolymer can be changed into a good skin adhesive when it is mixed with tackifiers and oils. The advantage of this adhesive is that it can be coated with hot melt coating process... [Pg.2927]

Anionic polymerization of lactams offers the best approach to the preparation of polyamide containing block copolymers. Styrene-nylon 6 block copolymers were prepared by adding e-caprolactam to polystyrene macroanions terminated with bisphenol A bis(chlorofor-mate)(31). Yamashita prepared ABA block copolymers of styrene-a-pyrrolidone and styrene- -caprolactam by sequential addition to styrene macroanions( ). Similarly Stehlik and Sebenda prepared N-acrylamide containing block copolymers(33). Block copolymers of isoprene-pivalolactam have also been reported( . In these cases the lactam was added to "living" polyisoprene anions. [Pg.91]

The strategies used to produce block copolymers can be well demonstrated with the example of a three-block copolymer, (styrene) Jbutadiene) -(styrene), which is commercially available as a thermoplastic elastomer (see Sections 5.5.4 and 25.3.11) This three-block copolymer can best be produced in a two-stage process with bifunctional initiators. Sodium naph-thalide or dilithium compounds can be used as initiators (see Section 18.1). Styrene is added on to the dianion produced and S B S is formed. The initiators mentioned above, however, are only effective in tetrahydro-... [Pg.820]

Styrenk Block Copolymers. Styrenic TPEs are copolymers whose molecules have the S-D-S structure, where S is a hard segment of polymerized styrene or styrene derivative, and D is a soft central segment of polymerized diene or hydrogenated diene units. Polybutadiene (B), polyisoprene (I), and polyethylenebutylene (EB) are the most commonly used rubbery segments (D). Structures for these triblock copolymers are represented as follows ... [Pg.303]
