... 536,756. Rubber sheets. DUNLOP RUBBER CO., Ltd., MADGE, E. W., and PURKIS, F. T. June 25, 1940, No. 10858. [Class 70] Rubber sheeting is prepared by applying a frothed aqueous dispersion of rubber to a backing surface, causing it to set to an irreversible spongy or cellular material, compacting the material by pressure while in the wet condition and drying. The dispersion may be treated to render it capable of gelling on application of heat or in the cold after a definite lapse of time ; as described in Specification 332,525, [Class 70]. If made from an uncompounded latex and unvulcanized, the sheet has high swelling properties without rapid dissolution in petrol &c. and may be used for covering petrol and other fuel containers. If made from a dispersion containing vulcanizing and other compounding ingredients it has a high resistance to tear, which may be enhanced by cold calendering of the sheet before vulcanizing.

Номер: CA0002343197A1

The invention disclosed provides a method for inducing nucleation in a polymer by subjecting the polymer containing dissolved gas to an external stress generated, for example, by applying hydrostatic or mechanical pressure. The applied stress restricts the bubble growth so that the foamed materials have small cells and high cell density. Such microcellular foams can be produced over a wide low temperature range, i.e. from the temperature at which the polymer is conditioned with the blowing agent up to about the glass transition temperature of the polymer-blowing agent system. Stress induced nucleation can also be conducted at higher temperatures i.e. up to about the Tg of the neat polymer, leading to foams with larger cells. A variety of homogeneous and heterogeneous foams can be produced by this technique.

Therefore, positive and negative charges in an apparently polarized state are present in the interfacial portions between the two types of synthetic resins incompatible with each other. By applying an external force to the electret sheet to deform it, the relative positions of these positive and negative charges are changed, and these changes cause a favorable electrical response.
