The polymerization of 2a in 1 mL 1-chloronaphthalene leads, after 24 h heating at 220[degrees]C, to the formation of the polymer 3a.
The polymerization of 2b was also performed at 220[degrees]C in inert atmosphere for 1 h in melt and for 24 h in a solution of 1-chloronaphthalene. Under these conditions, prepared polymers were isolated by precipitation as white or pinkish powder.
Polymerization of monomers in the solution of 1-chloronaphthalene provided also polymers with molecular weight similar to the melt polymerization.
Recently, additives such as diiodooctane (DIO) [10, 11], 1,8-octanedithiol (OT) [12],
1-chloronaphthalene (CN) [13], and nitrobenzene (NB) [14] have been introduced to change the morphology of the BHJ layer.
The dimensions and shapes of the manifold and the slot section in the end-fed coat-hanger die for the example calculations are given in Table 1, and the polymeric liquid we selected for illustration was a solution of linear polystyrene dissolved in
1-chloronaphthalene (24).
The molecular weight distribution of linear PPS for each as molded fracture toughness test specimen was determined by gel permeation chromatography (GPC) with a flame ionization detector at high temperature above 200 [degrees] C in
1-chloronaphthalene. The calibration curve was determined by polystyrene standards and tetramer of PPS.
