A method of producing solvent-soluble chlorinated polyolefin as resin for paint, ink, adhesion and film-forming uses comprising suspending polyolefin powder finely pulverized to a specific surface area of 300 to 20,000 cm.sup.2 /g into aqueous medium and conducting chlorination.

Method of producing chlorinated polyolefin

The present invention aims at providing a coating system which is capable of uniformly applying coating materials mixed with aggregates with a low fluidity as well as homogeneity on a base material and at remarkably enhancing productivity in the coating process. The coating system according to the present invention is characterized by the provision of a hopper to contain the coating materials mixed with aggregate arranged at a position so as to place a material outlet port of the hopper above a base material conveyer and of at least one levelling roller which is rotated in the same direction as the advancing direction of the base material, and arranged at a position above said base material conveyer but ahead of said material outlet port in the advancing path of the base material. The levelling roller rotates at a higher peripheral speed than the speed of the base material conveyor.

A method for producing a synthetic crystalline thermoplastic resin film suitable for stretching without necking including adding 5 to 300 parts by weight of a filler to 100 parts of a synthetic crystalline thermoplastic resin film such as polyethylene on isotactic polypropylene having a degree of crystallization of more than 60%, pressing the film against a rigid blade having a radius of curvature of 0.01 to 1.0 millimeter, bending the film around the blade using the blade as a fulcrum to a bending angle between 20.degree. and 170.degree., moving the film relative to the blade while keeping the bending angle constant thereby whitening the film, said whitening of the film being conducted without positively heating or stretching the film, and stretching the film after whitening at a draw ratio below the natural draw ratio of the film.
