[0052] (Preparation method of resin (A))
[0053] The method for producing the resin (A) is not particularly limited as long as it includes at least modifying the polyolefin (a) with the acid component (b). For example, a method of graft-modifying polyolefin (a) with an acid component (b), preferably a radical reaction between polyolefin (a) and acid component (b) in the presence of a radical generating agent Methods.
[0054] (free radical generator)
[0055] The radical generator can be appropriately selected from known radical generators, and organic peroxide-based compounds are preferred. Examples of organic peroxide-based compounds include di-tert-butyl peroxide, dicumyl peroxide, tert-butyl cumyl peroxide, benzoyl peroxide, dilauryl peroxide, hydrogen Cumene peroxide, tert-butyl hydroperoxide, 1,4-bis[(tert-butylperoxy)isopropyl]benzene, 1,1-bis(tert-butylperoxy)-3,5,5-tri Methylcyclohexane, 1,1-bis(tert-butylperoxy)-cyclohexane, cyclohexanone peroxide, tert-butyl pe...
example 2
[0090] The modified chlorinated polyolefin resin (X1) can be obtained by chlorination at any stage of preparation. As the stage of chlorination, for example, (Example 1) chlorination of polyolefin (a) (before graft polymerization of acid component (b)), (Example 2) chlorination of resin (A) (acid component (b) After graft polymerization), (Example 3) After modification with alcohol (B), Example 1 and Example 2 are preferred, and Example 2 is more preferred. That is, it is preferable that resin (A) is an acid-modified chlorinated polyolefin resin (A1).
[0091] Chlorination may be any method as long as it is a method of introducing chlorine atoms into the object, for example, the method of dissolving the object in water, carbon tetrachloride, or a chlorine-based solvent (e.g., chloroform) and then blowing chlorine gas . When blowing chlorine gas, ultraviolet rays may be irradiated as needed, and a radical reaction initiator may be present. As a radical reaction initiator, fo...
Embodiment
