Definitions
- a laminated etructure comprising at least two tubetratee bonded together by a melt adhesive comprising a linear condensation polyester derived from (A) at least one difunctional carboaylic acid and (B) at least one ditunctional dihydroxy component aelected from the group coaching of (l), a 2.2.4.4-tetraalkyi-13-cyclobw tanediol and (2) a mixture compoeed of a 2,2,4,4-tetraalkyHJ-cyclobutanediol and up to 95 mol percent of said mixture of a difierent difunctional dihydroxy compound, wherein said 2,2,4,4-tetraalkyl-1,3-cyclobutanediol isaelectedtrcmthegroupconaistingotitecisandtnm isomer: and mixtures tbereo!
- the term polyeater include: both polyester: and polycarbonate: such as the bisethyl carbonate ester of 50% oil 2,2,4,4-tetramethyl-1,3-cyclobutanediol.
- the melt adhesive is advantageous for use in laminated structures which must withrtand extreme temperature diflcrentialr.
