FIELD: process engineering. ^ SUBSTANCE: this invention relates to non-sticking multilayer elastomer film and to method of its production. Proposed film comprises first fragile polymer film layer that may not expand to over 110% of its initial size without breakage or cracking, and second elastomer layer. Said first layer is bonded with first surface of said second elastomer layer. First layer represents polystyrene while second layer is selected from the group comprising block-copolymer of styrene and elastomer of polyolefin. Multilayer may be activated by breaking first fragile polymer layer and imparting elastoplasticity to multilayer film. Film layer that may expand to approx. 150% of its initial size and recover after expansion to not over 120% of its initial size. Proposed method comprises producing non-sticking multilayer film layer and activating non-sticking multilayer film with destruction of fragile polymer film layer along with imparting elastoplasticity to multilayer film. ^ EFFECT: possibility to roll elastomer film and store without its sticking. ^ 19 cl, 8 dwg, 2 ex РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) 2 434 753 (13) C2 (51) МПК B32B B32B B32B B32B B32B B29C 3/10 (2006.01) 25/08 (2006.01) 27/34 (2006.01) 27/36 (2006.01) 27/40 (2006.01) 47/06 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ, ПАТЕНТАМ И ТОВАРНЫМ ЗНАКАМ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (21)(22) Заявка: 2007146144/04, 12.05.2006 (24) Дата начала отсчета срока действия патента: 12.05.2006 (73) Патентообладатель(и): КЛОУПЭЙ ПЛЭСТИК ПРОДАКТС КОМПАНИ, ИНК.

Improvements in or relating to photo-mechanical printing surfaces and processes

A neutral solution of casein, legumin, gluten or fibrin or a combination of these, is prepared by obtaining these substances as a highly pure precipitate acid dissolving it in a suitable acid or acid solution. The casein, legumin, gluten or fibrin is subjected to an initial purification by treating it with hot water or steam and then dissolving it in an alkaline or ammoniacal solution, thereby purifying it of fat and albumen. Precipitation is effected with oxyglutaric acid and the precipitate washed, separating from casein the soluble lime salts, or in the case of legumin or fibrin being precipitated to separate the insoluble gluten. The pure precipitate is dissolved in glutamic acid and dilute ammonia to obtain the neutral solution.

When the external pressure is rapidly dropped, the material explodes as the supercritical gas absorbed into the material rapidly expands outward.

Morphology trapping and materials suitable for use therewith

This invention is directed to a process for the rapid in-situ curing of polymerizable materials to provide macromolecular networks and articles of manufacture that are “morphology-trapped”; that is, they exhibit a fixed phase morphology and/or molecular orientation that is locked in by the curing step. The process includes the steps of mixing together a dead polymer, a reactive plasticizer and an initiator to give a polymerizable composition; further processing the mixture in order to achieve a desired phase morphology and/or molecular orientation of the polymeric constituents; shaping the polymerizable composition into a desired geometry; and exposing the polymerizable composition to a source of polymerizing energy, without mixing, to give a final product with the desired phase morphology and/or molecular orientation locked in place. The phase morphology and molecular orientation present just prior to cure of the polymerizable composition is subsequently trapped or locked in place by the curing step so that further changes in morphology are hindered or prevented.
