Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
71 words
In the process for the preparation of a plasticized polyvinyl butyral sheeting suitable for use in safety glass laminates, the improvement which comprises immersing the polyvinyl butyral sheeting in a solution of divalent metal salt of neo decanoic acid wherein the metal is magnesium or calcium wherein the amount of said neo decanoic acid salt incorporated into the polyvinyl butyral is about from 0.01-0.5 wt. percent based on plasticized polyvinyl butyral.
Claim 2
Dependent Claim
71 words
In the process for the preparation of a plasticized polyvinyl butyral sheeting suitable for use in safety glass laminates, the improvement which comprises immersing the polyvinyl butyral sheeting in a solution of divalent metal salt of neo decanoic acid wherein the metal is magnesium or calcium wherein the amount of said neo decanoic acid salt incorporated into the polyvinyl butyral is about from 0.01-0.5 wt. percent based on plasticized polyvinyl butyral.
Claim 3
Dependent Claim
20 words
A process of claim 1, wherein the solution further comprises about from 0.01-1.0% by weight of non-ionic or anionic surfactant.
Claim 4
Dependent Claim
64 words
In the process for the preparation of sheeting suitable for use in safety glass laminates by extruding a blend of polyvinyl butyral and plasticizer in the form of a sheet, the improvement which comprises incorporating into the blend prior to extrusion about from 0.01-0.5 weight percent of a divalent metal salt of neo decanoic acid wherein the metal is zinc, magnesium, calcium or lead.
Claim 5
Dependent Claim
