Abstract: There are provided orthopedic casts, splints, and the like, for use on a portion of a human or animal body, which are produced from a crosslinked copolymer of a lactone monomer and a polyfunctional acrylate monomer. The crosslinked copolymer, in the form of a sheet, web, bandage, etc., and, optionally, a supportive substrate, is heated above the softening point of the copolymer, manipulated to conform to the body portion, and cooled to a rigid state.In one embodiment, there is provided a bandage material, convertible to a rigid, porous, light-weight orthopedic cast, which comprises a substrate in the form of a netting, having on the surfaces of its strands a coating of the aforementioned crosslinked copolymer. The bandage material is heated to a temperature at which the crosslinked copolymer is soft and self-adherent and is then wrapped around the body portion in a series of overlying layers so as to conform to the contours of the body portion.

Abstract: Foamed, low density polymeric articles have been fabricated from a non-tacky hydrogel obtained by blending normally solid thermoplastic polymer resin with a normally liquid organic solvent and water, at lower molding temperatures and energy requirements than those conventionally used in melt extrusion foam processing.

Abstract: Thermoplastic, crosslinkable copolymer is produced by reacting an active-hydrogen containing initiator with a lactone monomer, such as epsilon-caprolactone, and a polyfunctional acrylate, such as neopentyl glycol diacrylate. The copolymer can be crosslinked by exposure to ionizing or actinic radiation or by free-radical peroxide catalysts. The degree of crosslinking can be controlled to produce a material which is thermoplastically processable and displays modified rheological properties which make it more easily processable than the corresponding lactone homopolymer.
