Polymer containing main-chain

Polymerisation of conjugated dienes can frequently lead to the formation of linear polymers containing main chain double bonds. Examples of such diene... [Pg.280]

Bis(oxazoline) ligands have also been used to produce polymers containing main chain chirality. Some examples include those by Wagner and co-workers in which /-pr-box 45 is used to mediate the copolymerization of tert-butylstyrene 192 with carbon monoxide to achieve a polymer of type 193 with stereoregularity up to 98%, ° ° Oishi and co-workers polymerization of A-substimted maleimides...

The synthesis of polymers containing main-chain cobaltocenium units has also been studied as this 18-electron organometallic moiety is isoelectronic with ferrocene. The synthesis of partially soluble polyesters (4.6, E = 0, R=(CH2)4, CH2C6H4CH2) was reported using solution condensation polymerization techniques, and the soluble fractions were of low molecular weight (M 2500-4000,...

Cytec has produced Cyasorb UV 3529, a stabiliser with low basicity and again, increased resistance to pesticides. It is a polymer containing main chain hexane diamine units, substituted piperadinyl units, and trichlorotriazine groups. [Pg.140]

Dynamic polymers containing main-chain hydrogen bonds have been studied extensively, among others thanks to their peculiar, but outstanding material properties. However, as the ultimate goal in DCC comprises temptation and isolation of particular sequences or conformations, we focus here on the kinetically more stable main-chain covalent polymers. [Pg.156]

The Norrish I and II reactions may occur from the excited singlet (S ) or triplet (T ) states however the triplet state is much more favoured because of its longer lifetime (Table 1.1). Both Norrish reactions are responsible for the photodegradation of polymeric ketones (cf. section 3.2.1) and polymers containing main chain carbonyl groups. [Pg.33]
