Abstract
The invention relates to compositions that are produced using a mixture from two or more polyols and to a method for producing said compositions. The invention also relates to the use of said compositions as adhesives, sealing compounds, surface-coating agents, fillers or for producing molded parts.
Claims3
A crosslinkable polymeric composition comprising at least one crosslinkable polymer having one or more reactive silyl functional groups that are crosslinkable with or without a crosslinker, wherein the composition comprises either:
- a) a crosslinkable polymer whose polymer backbone includes a first polyether segment comprised of a plurality of polypropylene oxyalkylene units OX1 and a second polyether segment comprised of a plurality of poly tetrahydrofuran oxyalkylene units OX2;
- or
- b) a mixture of crosslinkable polymers comprising crosslinkable polymer a) and at least one first crosslinkable polymer whose polymer backbone includes a polyether segment comprised of a plurality of polypropylene oxyalkylene units OX1 and a second crosslinkable polymer whose polymer backbone includes a polyether segment comprised of a plurality of poly tetrahydrofuran oxyalkylene units OX2;
- and the polyether segment comprised of first oxyalkylene units OX1 and the polyether segment comprised of second oxyalkylene units OX2 have a weight ratio of 10:90 to 90:10.
A crosslinkable polymeric composition comprising at least one crosslinkable polymer having one or more reactive silyl functional groups that are crosslinkable with or without a crosslinker, wherein the composition comprises either:
- a) a crosslinkable polymer whose polymer backbone includes a first oxyalkylene unit OX1 and a second oxyalkylene unit OX2;
- or
- b) a mixture of crosslinkable polymers comprising crosslinkable polymer a) and at least one first crosslinkable polymer whose polymer backbone includes an oxyalkylene unit OX1 and a second crosslinkable polymer whose polymer backbone includes an oxyalkylene unit OX2;
- wherein the oxyalkylene unit OX1 is a polypropylene and the oxyalkylene unit OX2 is a poly tetrahydrofuran, and wherein the oxyalkylene unit OX1 and the oxyalkylene unit OX2 have a weight ratio of 10:90 to 90:10.
