A multilayer structure comprising a layer of film susceptible to melting when used in conjuction with a microwave susceptor, a layer of microwave susceptor material, and a layer formed from a crosslinked melt extrudable material does not melt when used in a microwave oven.

Non-melting microwave susceptor films

A multilayer structure comprising a layer of film susceptible to melting when used in conjunction with a microwave susceptor, a layer of microwave susceptor material, and a layer formed from a crosslinked melt extrudable material does not melt when used in a microwave oven.

Cationic polyvinyl alcohol is prepared by blending polyvinyl alcohol under high shear conditions, at 0.degree.-100.degree. C., with a small amount of water, a small excess of base, and a quaternizing agent containing a halohydrin radical and a quaternary ammonium group. The quaternization proceeds with acceptable conversions of about 35 to well over 50%. The quaternized polyvinyl alcohol has many applications, including use as a flocculating agent, as a stabilizing colloid, and in adhesive formulations.
