Abstract: Provided is a molded filter used for a flexible disposable bag which is produced so as to be capable of sucking and storing, for example, bodily secretions of a patient and being disposed when a fixed storage amount is reached, wherein a laminate of at least two elements of a powdered hydrophilic swelling agent and a charged nonwoven fabric, and more preferably, a laminate of three elements with a hydrophobic porous film added thereto, is used as a filter base material and the charged nonwoven fabric is arranged downstream of the powdered hydrophilic swelling agent in a direction of flow of expiratory air inside the body. Thus, the molded filter has functions of air permeability that is equal to or higher than a PE sintered body CMC filter, short term and long term waterproof properties, and a better microbial barrier property.

Abstract: A heat-resistnat wire is disclosed which comprises a line of copper or aluminum coated with a shielding material obtained by heating a mixture of: (A) an ethylenic copolymer comprised of ethylene and 0.1 to 20.0 mol % of a monomer of at most 30 carbon atoms having an oxirane group or a hydroxyl group and having at least one double bond; and (B) an ethylenic copolymer comprised of ethylene and 0.1 to 20.0 mol % of a monomer possessing a functional group capable of reacting with oxirane group or hydroxy group in the ethylenic copolymer (A). The wire is excellent not only in heat resistance but also in insulating ability and flexibility.

Abstract: A heat resistant printed circuit board is disclosed which comprises a laminate of:(A) a thin-walled body having a thickness of from 0.2 .mu.m to less than 5 mm and containing a cross-linked product of a mixture of (a) 1 to 99 wt. % of an ethylenic copolymer (A) comprised of 30 to 99.5 wt. % of ethylene, and an oxirane ring-containing compound having at least one double bond and having 6 to 30 carbon atoms, and (b) 99 to 1 wt. % of an ethylenic copolymer (B) comprised of 30 to 99.5 wt. % of ethylene, and a comonomer selected from the group consisting of unsaturated monocarboxylic acids, unsaturated dicarboxylic acids, unsaturated dicarboxylic acid anhydrides, and half esters of unsaturated dicarboxylic acids; and(B) an electrically conductive metal layer having a thickness of from 100 .ANG. to 400 .mu.m.The boards have excellent heat resistance, electrical insulating properties, flexibility, chemical resistance, dimensional stability, etc.
