The present invention provides a separator including a separator substrate composed of a polylactic acid film or sheet having tear strength so as not to break or tear during, for example, production or processing of the separator or winding thereof into a roll, and causing neither melt nor deformation at high temperatures more than 100°C. The separator according to the present invention is a separator including a separator substrate and a removable pressure-sensitive adhesive layer on at least one surface of the separator substrate, wherein the separator substrate is composed of a polylactic acid film or sheet comprising polylactic acid (A) wherein the tear strength of the film or sheet is not less than 100 N/mm when the film or sheet is torn at least in a flow direction (MD), a rate of dimensional change due to heating is not more than ±3% in the flow direction (MD) and a transverse direction (TD), and a rate of dimensional change due to loaded heating is not more than ±3% in the flow direction (MD).
摘要:
A flexible, calenderable film exhibiting enhanced durability under external weathering conditions. The film comprises predominantly a base layer of a graft copolymer of vinyl chloride on polyacrylate laminated with an acrylic based protective layer. Importantly, the base layer is devoid or contains minimal plasticiser components to eliminate or reduce UV absorber migration from the acrylic based protective layer.

Disclosed is a graft copolymer in which a polyalkylene glycol or an alkyl ether thereof is graft-copolymerized with a polyfluoro-1-alkene represented by the general formula: C n F 2n+1 (CH 2 CF 2 ) a (CF 2 CF 2 ) b CH=CH 2 (wherein n is an integer of 1 to 6, a is an integer of 1 to 4, and b is an integer of 1 to 3). The graft copolymer is an oligomer compound having a perfluoroalkyl group containing 6 or less carbon atoms, which is said to have low bioaccumulation potential, and having, when used as an active ingredient of a mold-releasing agent, mold release performance equivalent to that of a compound having a perfluoroalkyl group containing 8 or more carbon atoms.

摘要:
Provided are functionalized polypropylene adhesive compositions having a desirable range of melt flow rate. These compositions are obtained by grafting at least one impact polypropylene copolymer or by co-grafting a blend containing at least one impact polypropylene copolymer and at least one random polypropylene copolymer. The polypropylene copolymer(s) are grafted with one or more ethylenically unsaturated carboxylic acids or derivatives of these acids, such as anhydrides. Maleic anhydride is a preferred grafting monomer. Also provided is a multilayer film or sheet structure containing at least one barrier layer and at least one adhesive layer produced from the functionalized polypropylene adhesive composition. The multilayer film or sheet structure may also contain at least one predominantly polypropylene-based layer. In addition, a multilayer film or sheet structure is provided in which a barrier layer or a primer layer is adjacent to at least one layer that is produced from a dry blend or a melt blend of the functionalized polypropylene adhesive composition with a polypropylene matrix polymer.
