Abstract
A resin composition comprising a polyolefin, carbon nanotubes and poly(hydroxy carboxylic acid). The invention also covers a process for preparing a resin composition comprising a polyolefin, carbon nanotubes and poly(hydroxy carboxylic acid) by (i) blending a poly(hydroxy carboxylic acid) with carbon nanotubes to form a composite (ii) blending the composite with a polyolefin. The use of poly(hydroxy carboxylic acids) as a compatibilizer to blend carbon nanotubes into polyolefins is also claimed.
