Abstract

Official abstract text for this publication.

Polymer film and laminated glass manufactured using the polymer film are provided. The polymer film has a first surface and a second surface, wherein the first surface has a peak material volume (Vmp) at a material ratio of 10% ranging from 0.15 μm3/μm2 to 1.20 μm3/μm2 and a kurtosis (Sku) ranging from 0.73 to 10.02, wherein the material ratio, peak material volume, and kurtosis are defined in accordance with ISO 25178-2:2012.

First claim

Opening claim text (preview).

What is claimed is: 1 . A polymer film, which has a first surface and a second surface, wherein the first surface has a peak material volume (Vmp) at a material ratio of 10% ranging from 0.15 μm 3 /μm 2 to 1.20 μm 3 /μm 2 , and a kurtosis (Sku) ranging from 0.73 to 10.02, wherein the material ratio, peak material volume, and kurtosis are defined in accordance with ISO 25178-2:2012. 2 . The polymer film of claim 1 , wherein the second surface has a peak material volume (Vmp) at a material ratio of 10% ranging from 0.15 μm 3 /μm 2 to 1.20 μm 3 /μm 2 , and a kurtosis (Sku) ranging from 0.73 to 10.02, wherein the material ratio, peak material volume, and kurtosis are defined in accordance with ISO 25178-2:2012. 3 . The polymer film of claim 1 , wherein the first surface and the second surface independently have a mean width of profile elements (Rsm) ranging from 10 μm to 660 μm, wherein the mean width of profile elements is defined in accordance with ISO 4287:1997. 4 . The polymer film of claim 2 , wherein the first surface and the second surface independently have a mean width of profile elements (Rsm) ranging from 10 μm to 660 μm, wherein the mean width of profile elements is defined in accordance with ISO 4287:1997. 5 . The polymer film of claim 1 , which has a glass transition temperature (Tg) ranging from 5° C. to 23° C. 6 . The polymer film of claim 2 , which has a glass transition temperature (Tg) ranging from 5° C. to 23° C. 7 . The polymer film of claim 1 , which comprises polyvinyl acetal. 8 . The polymer film of claim 2 , which comprises polyvinyl acetal. 9 . The polymer film of claim 7 , wherein the polyvinyl acetal is poly(vinyl butyral). 10 . The polymer film of claim 8 , wherein the polyvinyl acetal is poly(vinyl butyral). 11 . The polymer film of claim 7 , wherein the polyvinyl acetal has a number average molecular weight (Mn) ranging from 90,000 to 120,000. 12 . The polymer film of claim 8 , wherein the polyvinyl acetal has a number average molecular weight (Mn) ranging from 90,000 to 120,000. 13 . The polymer film of claim 7 , which further comprises a plasticizer. 14 . The polymer film of claim 8 , which further comprises a plasticizer. 15 . The polymer film of claim 13 , wherein based on 100 parts by weight of the polyvinyl acetal, the amount of the plasticizer ranges from 35 parts by weight to 50 parts by weight. 16 . The polymer film of claim 14 , wherein based on 100 parts by weight of the polyvinyl acetal, the amount of the plasticizer ranges from 35 parts by weight to 50 parts by weight. 17 . A laminated glass, which comprises a first glass sheet, a second glass sheet, and an intermediate film disposed between the first glass sheet and the second glass sheet, wherein the intermediate film is provided by the polymer film of claim 1 . 18 . A laminated glass, which comprises a first glass sheet, a second glass sheet, and an intermediate film disposed between the first glass sheet and the second glass sheet, wherein the intermediate film is provided by the polymer film of claim 2 .
