The experimental studies on phase behavior and pattern formation reviewed here have been done on substrate-supported films of cylinder-forming polystyrene- foc -polybutadiene diblock (SB) [36, 43, 51, 111-114] and triblock (SBS) [49, 62, 115-117] copolymers (Table 1), lamella-forming polystyrene- /ocfc-poly(2-vinyl pyridine) diblock copolymers (SV) [118, 119] and ABC block terpolymers of various compositions [53, 63, 120-131], In simulation studies, a spring and bid model of ABA Gaussian chains has been used (see Sect. 2) [36,42, 58, 59],... 

The formation of coagulum is observed in all types of emulsion polymers (i) synthetic rubber latexes such as butadiene-styrene, acrylonitrile-butadiene, and butadiene-styrene-vinyl pyridine copolymers as well as polybutadiene, polychloroprene, and polyisoprene (ii) coatings latexes such as styrene-butadiene, acrylate ester, vinyl acetate, vinyl chloride, and ethylene copolymers (iii) plastisol resins such as polyvinyl chloride (iv) specialty latexes such as polyethylene, polytetrafluoroethylene, and other fluorinated polymers (v) inverse latexes of polyacrylamide and other water-soluble polymers prepared by inverse emulsion polymerization. There are no major latex classes produced by emulsion polymerization that are completely free of coagulum formation during or after polymerization. 

Polybutadiene-f)-polystyrene [54-56], poly(dimethyIsiloxane)-h-polystyrene [57], PEO-b-PSt [58], and PEO-h-poly(4-vinyl pyridine) [59] copolymers were synthesized by terminating the corresponding hving anionic polymerization with a suitable TEMPO derivative and subsequent NMRP. 

Notes The values of A, B, and C and thus of y are based on a reference volume Vre/ = 0.1 nm Polymer notation A d- label preceding the polymer acronym indicates a per-deuterated polymer partially deuterated polymers are labeled as dy, df, etc., for selective deuteration of 3, 4, etc., hydrogens. Numbers in subscripted parentheses after the polymer name indicate the primary comonomer fraction, e.g., SPB(6s) is a saturated polybutadiene with 66 mol% butadiene Polymer acronyms P2VP poly(2-vinyl pyridine), P4MS poly(4-methylstyrene), PBMA poly(n-butyl methacrylate), PCHA poly(cyclohexyl acrylate), PEB poly(ethyl butylene), PIB polyisobutylene, PI polyisoprene, PMMA poly(methyl methacrylate), PPMA poly(n-pentyl methacrylate), PP polypropylene, HHPP head-to-head polypropylene, PS polystyrene, PVME poly(vinyl methyl ether), PXE poly(2,6-dimethyl-l,4-phenylene oxide), SPB saturated polybutadiene, SPI saturated polyisoprene...

A significant development was disclosed by Lin. He replaced part of the vinyl pyridine terpolymer latex in the adhesive recipe with poly butadiene latex. Glass cords dipped in this polybutadiene latex adhesive were more resistant to fracture under cold weather conditions. This was attributed to the lower tg of polybutadiene compared to vinylpyridine-styrene-bu-tadiene rubber.

Other attempts made by Rempp et al. [48, 49] and VoUmert et al. [50] used a similar method but changed the solvent conditions using, for example, a mixture of benzene and tetrahydrofuran (THF). This allowed good coupling for the synthesis of cyclic polymers with different building blocks such as poly(2-vinyl pyridine), polybutadiene, poly(dimethylsiloxane), poly(propylene oxide), poly(ethylene oxide), and a variety of other polymers (Scheme 4).

Phenyl terminated polybutadiene (M 1300 daltons, 45% vinyl) was reacted with trichlorosilane and chloroplatinic acid and then mixed with a slurry of 105 p particle size silica gel having a 250 A average pore diameter in dry toluene for 24 hours. The quantity of trichlorosilane used was 2 mol per mole of polybutadiene. Pyridine was added to remove HCl, and the slurry was gently shaken for 18 hours at ambient temperature. The surface of the silica was blocked by addition of 1,2-bis(trichlor-osilyl)ethane, and the mixture was treated with pyridine. After three hours of shaking the reaction was worked up by vacuum filtration in a sintered glass funnel and washed with toluene and methanol. The modified silica gel was dried in the filter funnel by continued application of vacuum to the filter funnel.
