Polyvinyl alcohol alloys. |
摘要 |
<p>A polymer alloy is prepared by reacting a polyvinyl alcohol polymer having a degree of hydrolysis of less than 98 mole percent with less than the stoichiometric amount of a functional olefin polymer containing functional groups which are reactive with the hydroxyl groups of the polyvinyl alcohol polymer whereby there is obtained a mixture of grafted and ungrafted polyvinyl alcohol polymers, the grafted polyvinyl alcohol polymer having less than all the available hydroxyl groups reacted with said functional groups.
<??>This polymer alloy may be blended with a compatible olefin homo- or co-polymer blending resin. </p> |
