An improved binder composition for use in the foundry process comprises a mixture of low molecular weight essentially mononuclear methylolated phenols which are cured through a reaction with a polyisocyanate. In the preferred embodiment, a minor amount of polyether polyol, a mutual solvent and a catalyst, preferably an amine catalyst, is mixed with the phenolic component.

Binder for foundry process

An acrylic polymer of one or more C.sub.10 to C.sub.22 methacrylates and one or more acrylic acids selected from the group consisting of acrylic acid and methacrylic acid useful as a modifier for polyolefins, the composition comprising polyolefin and a minor amount of the modifier, and a process for improving processability of polyolefin comprising blending therewith the above mentioned acrylic polymer.
