“…Properties of Polymer Films. Bisvinyl ether compound reacts readily with phenol or carbonyl groups of polymers above 80 o C, producing acetal structures between the vinyl group and phenol or carboxyl group [6,7,8]. The acetal structures cross-link the polymer into three-dimensional networks, while shield phenol or carbonyl groups of the polymer, reducing aqueous solubility of the polymer.…”

“…In this paper we synthesized a series of copolymers containing isobutyl p-styrenesulfonate (IBSS), which were stable below 100 o C and readily undergone acid releasing above 180 o C. Further, bisvinyl ether has been reported to be very reactive with carboxylic acid at suitable temperatures (typically between 80-120 o C) and could be used as an effective crosslinker for polymers with pendant carboxyl groups [6,7,8]. The bridging mechanism is the formation of acetal ester bond between the polymer chains through the reaction of carboxyl group with divinyl ether.…”

Three copolymers containing isobutyl p-styrenesulfonate (IBSS) and carboxyl units, i.e. methyl methacrylate (MMA) and methacrylic acid (MAA), were synthesized and their chemical structures and thermal behaviors were investigated by using TGA, DSC, FTIR and other methods. Films were prepared by using the synthesized copolymers in combination with a bisvinyl ether compound, i.e. 2,2-bis(4-(2-(vinyloxy)ethoxy)phenyl)propane (BVPP), to applied onto an aluminum plate. Crosslinking and de-crosslinking reactions would readily take place when the polymer films were baking treated at 100 oC and 200 oC for a short period of time, respectively. Along with the chemical structural changes during thermal treatments, an affinity change was achieved from being insoluble to completely soluble in neutral water. A positive-working and neutral water-developable imaging material was proposed and preliminary studies on the imaging properties were conducted.

“…Their particular properties make them attractive for several applications such as sheet carbon and copying paper, paints and varnishes, plasticizers, floor wax, chewing gum base, concrete curing, rubber belts and hoses, among others [2][3] . They can also be used in some reactions as cross-linker agents and precursors for light and thermal stabilizers [4,5] . As adhesion modifier these resins find applications in adhesives for nicotine delivery and surface-active agent in polymer/metal and polymer/polymer systems [6][7][8] .…”

Oligobetapinene as barrier improver to CO2 of HDPE in thin films of binary blends

2004

Quenched thin films (about 100 microns thick) of high-density polyethylene (HDPE) / oligobetapinene (OBP) blends were prepared by melt mixing with the amount of OBP varying from 0 to 40%. The results of CO2 permeation, thermal behavior and morphology are reported. From -130 to -100 °C we observed two peaks in DSC measurements, the lower one being ascribed to g-transition of HDPE. The upper one attributed to Tg which was shift at high contents of OBP. The OPB molecules also displayed another transition at higher temperatures. The normalized degree of crystallinity of HDPE remained constant while the overall crystallinity of the blends was reduced in all blends. We have hypothesized that three distinct phases coexist, viz. a HDPE-amorphous phase with some amount of OBP molecules, OBP-amorphous phase with polyolefin and HDPE-crystalline phases. The permeation test revealed a decrease in permeability to CO2 independent of the amount of OBP in the blends. The reduction of gas permeation could be explained mainly by the rigidity of the OBP rich phase that has counterbalanced the decrease of overall crystallinity of the film blends
