We have utilized somewhat less-effective optional approaches to copolymer purification with attendant catalyst recovery. One of these methods involved the replacement of the f-butyl substituents on the 5-position of the phenolate ligands with poly(isobutylene) (PIB) groups, as illustrated in Fig. 14 [39]. Importantly, this chromium(III) catalyst exhibited nearly identical activity as its 3,5-di-t-butyl analog for the copolymerization of cyclohexene oxide and carbon dioxide. The PIB substituents on the (salen)CrCl catalysts provide high solubility in heptanes once the copolymer is separated from the metal center by a weak acid. [Pg.15]

Enhanced radiation cross-linking in polyethylene, polypropylene, and poly-isobutylene and in copolymers of ethylene and propylene was found when nitrous oxide was incorporated into the polymer matrix. Mechanisms of fhis process have been proposed by several workers. ... [Pg.91]

We studied dienic elastomer films (EPDM, poly-octenamer, poly-isobutylene-co -iso-prene) which react with singlet oxygen, 02, according a "ene" reaction described elsewhere1 12. The resulting hydroperoxidized polymers can also be treated by nitric oxide and acetyl chloride but the reactions result now in the formation of nitrate and perester respectively ... [Pg.25]

Poly(isobutylene) dicarboxylic acid was prepared by oxidation of the copolymer of isobutylene with a diene 53,54). The most efficient oxidizing agent was the system KMn04-periodic acid. Oxidation of a copolymer of isobutylene and 2,3-dimethyl-butadiene afforded a polymeric bis-ketone54). [Pg.91]

McCrum [213, 214] recently suggested that the above approach is subject to large errors and based on an irrational premiss. He proposed a new method of thermoviscoelasticity . Smith and Mark [215] have demonstrated McCrum s analysis to be flawed and have shown that the classical thermoelasticity approach is soundly based on theory. Indeed, there is excellent agreement between thermoelastic and viscometric results for poly(l-pentene) [206, 211], polyethylene [151, 154, 155, 211, 216], poly(dimethyl siloxane) [205, 211, 217], poly(ethylene oxide) [211, 218], poly (isobutylene) [207, 211, 216, 219] and poly(H-butyl methacrylate) [220, 221] (Table 6).

The majority of the early work involving the layer-by-layer process involved inorganic substrates such as quartz and silicone since it was thought that the process required flat clean surfaces. Later on polymer films and other organic materials were used as substrates. Some of the most studied polymers include poly(propylene) (PP), poly(isobutylene) (PIB), poly(styrene) (PS), poly(methyl methacrylate) (PMMA), poly(ethylene terephthalate) (PET), poly(phenylene oxide) (PPO) and poly(ether imide) (PEI). ...
