A laminar structure comprised of at least one layer of glass and a sheet of plasticized PVB containing an adhesion control agent is provided wherein pin point pockets of air which are entrapped in said sheet coalesce and cause delamination of said structure, delayed delamination and associated defects are prevented by adding a nucleating agent with the plasticized PVB by coating the sheet or glass surface with a nucleating agent, by extruding the PVB sheet with the nucleating agent in the composition, or by forming the nucleating agent in situ during the extrusion or lamination process.

A thermoplastic film having dispersed therein an inert material consisting essentially of:1. coarse particles having a size greater than 2.5 microns in a concentration determined by the formulaC.sub.1 = K.sub.coarse/T 0.6where C.sub.1 is the concentration of coarse particles in parts per million, K.sub.coarse is at least equal to an emperically determined value of K.sub.coarse at the minimum concentration of coarse particles which permits escape of air during film wind-up, and T is film thickness in mils,2. medium particles having a size of 1 to 2.5 microns in a concentration determined by the formulaC.sub.2 = K.sub.medium/T 0.6where C.sub.2 is the concentration of medium particles in parts per million, K.sub.medium is no greater than an emperically determined value of K.sub.medium at the concentration of medium particles in a film having a clarity of 50%, and T is film thickness in mils, and3. fine particles having a size less than 1 micron in a concentration determined by the formula:C.sub.3 = K.sub.fine/T 0.6where C.sub.3 is the concentration of fine particles in parts per million, K.sub.fine is at least equal to an emperically determined value of K.sub.fine at an effective concentration of fine particles to give a film static coefficient of friction less than about 1, and T is film thickness in mils, with the provisos that:A. the total K.sub.total = K.sub.coarse + K.sub.medium + K.sub.fine is equal to or less than about 2,510, andB. the ratio of K.sub.medium /K.sub.total is equal to or less than about 0.3Also a process for preparing the film. The filler material provides excellent winding characteristics while maintaining commercially acceptable clear films.
摘要:
This invention relates to thermoplastic interlayers for laminated safety glass with superior vacuum de-airing at elevated temperatures and superior tacking and edge sealing properties. The sheeting has surface pattern on at least one of the surfaces characterized by flat surfaces with substantially uninterrupted channels for airflow in at least two non-parallel directions. The channels allow for rapid de-airing while the area roughness parameter ratio ARp/ARt in the range of 0.52 to 0.62, ARt being less than 32 μm, and area kurtosis less than 2.5, allow for ease of tacking of the interlayer onto glass and edge sealing after de-airing has been completed. Said surface pattern may also be superimposed onto a pattern which is generated by melt fracture or other means on at least one side to enhance de-airing and aid edge sealing.
