Beschreibung
Zusammenfassung:	A method of producing plasticized partial polyvinyl butyral sheet (10) having a desired level of potential adhesion to glass which comprises: i) providing partial polyvinyl butyral resin having a high affinity for adhesion to glass when in sheet form under laminating conditions of elevated temperature and pressure; ii) mixing the resin with plasticizer to form a heat-shapable formulation; iii) extruding the formulation to form a sheet, and formulation; iv) applying a multiplicity of spaced anti-adhesion projections (16) to the surface of the sheet (10) to an extent effective to counteract the high adhesion of the sheet to glass between projections.
