ABSTRACT:
The present invention relates to a process and a composition for the manufacture of an artificial paper requiring neither calendering nor biorientation, the paper obtained having in addition to the characteristics proper to cellulose paper, improved physical properties, such as better impermeability to water vapor and air, resistance to greases and dimensional stability under various atmospheric conditions.
The paper is produced by homogenizing in a conventional rotary mixer a composition containing (a) a specific class of rigid polyolefins which provides the necessary stiffness of the paper and constitutes its framework, (b) a polymer which is incompatible with the rigid polyolefin selected from the homopolymers and copolymers containing a preponderant amount of styrene and which provides the hardness and tearability of the paper, (c) a macromolecular material producing compatibility between (a) and (b) which is a mixture prepared in advance from at least one homopolymer of ethylene, propylene or butylene, and at least one homopolymer of isobutylene, butadiene or isoprene, or butyl rubber, and (d) an inorganic filler, subjecting the thus homogenized mixture directly to extrusion to form a material which is suitable as such as a paper substitute, in the absence of further biorientation.
