DICINNAMYLIDENE HEXANEDIAMINE

A Viton-HV poly(VDF-co-HFP) copolymer with a molar percentage of HFP of 28.5%, in the presence of 5 parts of MgO per hundred parts of rubber (phr), was vulcanized with different phr of Diak No3 (Ar,M -dicinnamylidene-l,6-hexanediamine) [27]. 

Tables Evolution of the glass transition temperature (Tg, °C) of samples A-1 to A-7 (indicated in Table 7) with the amounts of N,N -dicinnamylidene-l,6-hexanediamine [27] ...

Kalfayan [118] and Thomas [24] studied the stress relaxation of poly(VDF-ter-HFP-ter-TFE) terpolymers crosslinked with N,N -dicinnamylidene-l,6-hexanediamine, and of a poly(VDF-co-HFP) copolymer crosslinked with HMDA-C, respectively. 

Other mechanical properties and resistance to bases and to acids are studied for a poly(TFE-alt-P) elastomer cured with a peroxide (o, Q -bis-(t-butylperoxy)-p-diisopropylbenzene), and a poly(VDF-ter-HFP-ter-TFE) ter-polymer cured with a diamine (NyN dicinnamylidene-l,6-hexanediamine) (Table 24) [39].
