Spectrum of the copolymer to fully crowded gem-dimethyl sequences, i.e., isobutylene-isobutylene or ii for brevity, sequences. Poly(jS-pinene), a molecule that contains uncrowded gem-dimethyl groups, shows a resonance band at 0.85. On the basis of this, we assigned the band appearing at 0.8 5 in the spectrum of the copolymer to uncrowded gem-dimethyls indicating a P-pinene unit that is followed by another j3-pinene unit i.e, flS sequences. The central band at 1.05 of the three partially unresolved bands in the spectrum of the copolymer is a new gem-dimethyl band...

An example of an enantiomerically pure polymer is also shown [11]. Aoki et al. showed that films of a polyacetylene substituted with a (-)-p-pinene derivative formed an effective membrane for chromatographic resolutions of racemic mixtures. ( )-2-Butanol was resolved to 29.8% eje. and unsaturated polymers for both liquid-phase and gas-phase separation applications (8, 9, 79]. It has been suggested that the rigidity and irregularity of the highly substituted polyacetylene chain, combined with the presence of aliphatic substituents which reduce interchain interactions, are important for the polymers transport properties [10]. 

Production By steam distillation of the seeds (nutmeg) and seed husks (mace) of Myristica fragrans. CompositionThe oils contain as main components monoterpene hydrocarbons such as a-,p- pinenes and sabinene (see thujenes), ca. 20-30% of each. The components responsible for the odor and taste include small amounts of terpinenol-4 (see p-menthenols), safrole, eugenol, and isoeugenol. A characteristic compo-...
