“…polymerizing with additional backbone components [9][10][11], cross-linking [12][13], end-capping [14][15][16] and hydrogen-bonding [17][18][19][20][21][22]. In these methods, performance improvement of polymer blends or composites via the hydrogen-bonding interaction is a rather effective method.…”

Impact strength, initial decomposition temperature and glass transition temperature of pure PPC and PPC/SF-PA66 composites Via hydrogen-bonding interaction, poly(propylene carbonate) (PPC) was firstly reinforced by polyamide 66 short fiber (SF-PA66). The tensile and impact strength, thermal stability of composites increased when the SF-PA66 content ranges from 5% to Downloaded by [UNSW Library] at 03:31 19 August 2015 2 20%, then decreased at 30%. The increment in impact strength, decomposition temperature of 5% mass loss and glass transition temperature of PPC/20%PA66 is 315.81%, 32.2 °C and 3.8°C, respectively. FTIR and 1 H NMR results illuminate that the introduction of hydrogen bonding interaction between PPC and SF-PA66. Moreover, the network structure formed when SF-PA66 content is higher than 20 wt%. It is confirmed by rheological responding curves that a plateau at low angle frequency occurs. In addition, a significant aggregation of SF-PA66 occurs when its content is 30 wt%, which causes the decrease in mechanical and thermal properties of PPC/SF-PA66 composites.

“…Yao et al and Peng et al showed that the decomposition temperature increased by mixing MAH with PPC. Barreto et al found that large quantities of MAH can reduce viscosity and Mw of PPC compounds. Our previous works describe a detailed examination of the melt compounding of PBS and PPC with varying amounts of MAH and a peroxide initiator.…”

Macro Theory & Simulations

The functionalization of poly(propylene carbonate) (PPC) by means of both free radical and esterification grafting of Maleic anhydride (MAH) aided by a peroxide is simulated by means of a kinetic model. The amount of MAH grafted (Ag) measured from batch mixer trials shows good agreement with the simulated results. Sensitivity analysis of the different rate constants shows that peroxide decomposition is the factor that drives the reaction, meaning that the choice of initiator affects greatly the reaction conversion. The next most dominant reaction is the chain ends esterification. There is a competing effect between chain initiation and side reactions, however, chain initiation is slightly more dominant than the latter. It is also found that higher content of peroxide induces higher Ag. The amount of MAH has a lower impact on Ag at low peroxide concentration; however, it becomes more influential in the presence of more peroxide.
