Disclosed is a foldable electronic device including a sealing member for protecting a side surface of flexible display. A foldable electronic device according to various embodiments of the disclosure may include: a foldable housing configured to be folded and unfolded, a flexible display disposed in the foldable housing, the flexible display including a display panel configured to display image information and a cover window covering a first surface of the display panel on which image information is displayed, the display panel having at least one portion configured to be bent according to folding and unfolding operations of the foldable housing, and a seal contacting a region of a side part of the flexible display with reference to the first surface of the flexible display, the region including a space between the cover window and the display panel, wherein the seal may include a polymer material which is configured to be bent according to the bending operation in a state of being in contact with a side surface of the flexible display during the bending operation of the flexible display.

Polythioether prepolymers that have a low nucleation temperature. The symmetry of the polythioether prepolymers is modified by including pendent groups extending from the backbone of the polythioether prepolymer chain and/or the symmetry is modified by including segments having a different number of —C(R).sub.2— groups between heteroatoms. The polythioether prepolymers are stable at low temperature storage conditions for an extended period of time. Compositions prepared using the low nucleation temperature polythioether prepolymers are useful as sealants.

A vessel closure (1, 21, 41, 61) includes a sealing element (3, 23, 43, 63). The sealing element (3, 23, 43, 63) includes a polymer composition. The polymer composition includes a polyalphaolefin with kinematic viscosity, determined according to ASTM D445 / ISO 3104, of at least 4 cSt, at a temperature of 100° C., and/or a dropping point, determined according to ASTM 5950, of at most -10° C., and up to 95% by weight of a second polyolefin.

A sealant material for sealing joints between male and female mating parts comprising: (a) an elongate flexible thread suitable for wrapping around at least one of the parts, and (b) a joint sealing composition comprising an anaerobically curable composition in solid form,
the flexible thread being coated with the anaerobically curable composition. This provides a reactive composition on the thread for sealing joints.
