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 invention relates to a method for producing solvent-soluble chlorinated ethylene-vinyl acetate copolymer by conducting homogeneous chlorination of ethylene-vinyl acetate copolymer in aqueous suspension by irradiation or by organic or inorganic radical generation, which method comprises conducting the chlorination upon a powder of ethylene-vinyl acetate copolymer containing 5 to 35 wt % of vinyl acetate and having a specific surface area of not less than 300 cm.sup.2 /g at a reaction temperature dependent upon the content of vinyl acetate as expressed in the relationship:

Method of producing chlorinated EVA

Rapidly curable adhesive compositions suitable for bonding polypropylene, comprising a polymer of sulfochlorinated and/or chlorinated polypropylene with an average chlorine content of 26% to 34% by weight, and an average molecular weight of 5,000 to 120,000, dissolved in monomeric ingredients such as acrylic and/or methacrylic monomers.

Rapidly curable acrylic adhesive compositions for bonding polypropylene

A film-forming composition containing a chlorinated polyolefinglycol as a binder component which is obtained by uniformly chlorinating in solution polyethyleneglycol and/or polypropyleneglycol having a molecular weight not lower than 200 to a chlorine content of 50-75% by weight.

Film-forming composition comprising chlorinated polyalkylene glycol

This invention relates to a chlorinated polymer and a coating composition employing the same which is characterized by being comprized of chlorinated polymethylpentene obtained by uniformly chlorinating an isotactic poly-4-methylpentene-1 having the melt index of 8-70 g/10 min. at 260.degree. C. and 5 kg, (ASTM D 1238-65T) in a solution thereof, to not less than 50 weight % of chlorine content.
