Possessive adjectives are not pronouns, but they are important to learn before studying Possessive Pronouns below. Possessive Adjectives are used before nouns to identify the owner of something:

Where's Paul? This is his jacket.


Where's Paul? This is his.

Notice the differences between subject pronouns, object pronouns, and possessive adjectives:
