Abstract
Compositions comprising a novolac polymer, an olefin-based polymer with an epoxy group, a filler and optionally a thermoplastic polymer are provided. The compositions may be halogen-free. The present compositions exhibit excellent compatibility between the novolac polymer and the olefin-based polymer with an epoxy group resulting in compositions with superior mechanical properties.
Claims20
A composition comprising:
- about 15 wt % to about 30 wt % of a novolac polymer;
- about 0.1 wt % to about 10 wt % of an olefin-based polymer with an epoxy group;
- and
- greater than 0 wt % to about 70 wt % of a filler.
1 more element
A process for producing a heterophasic composition comprising:
