There is disclosed a novel class of coupling agents for chrysotile asbestos and thermoplastic polymers. The coupling agents comprise certain phenolic materials, and their use as coupling agents in chrysotile asbestos-reinforced thermoplastic polymers serves to impart, at relatively low cost, a unique and valuable combination of properties to the said reinforced polymers. Preferred coupling agents are illustrated by 2,6dimethylol-4-alkylphenols and oligomers and polymers thereof. |
