Abstract: 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.

Abstract: A plastic sheet (10) preferably of plasticized partial polyvinyl butyral, for a laminated safety glazing, having means (16) dispersed on its surface, preferably comprising a multiplicity of spaced projections, capable of resisting adhesion to a rigid panel, such as glass, of such a glazing when the sheet is laminated to the panel, the area of the sheet surface without such dispersed means having high affinity for adhesion. The projections (16) physically block adhesion of a dispersed area of the sheet to the panel in that the means on the sheet surface have no or weak interfacial adhesion. The multiplicity of space projections also have low or no affinity for adhesion when in blocking contact with each other or with another plasticized partial polyvinyl butyral surface and thereby increase blocking resistance.

Abstract translation: 用于层压安全玻璃的优选塑化部分聚乙烯醇缩丁醛的塑料片（10）具有分散在其表面上的装置（16），优选地包括多个间隔开的突起，能够抵抗诸如玻璃之类的刚性面板的粘附， 当片材层压到面板上时，没有这种分散方式的片材表面的区域对粘合具有高亲和力。 突起（16）物理上阻挡了片材分散区域与面板的粘附，因为片材表面上的装置没有或具有弱的界面粘合。 空间突起的多重性当彼此阻塞接触或与另一种增塑的部分聚乙烯醇缩丁醛表面相比时，粘合性也低或没有亲和力，从而增加了抗粘连性。
