## 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.

## Claims

### Claim 1

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.

### Claim 2

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.

### Claim 3 (depends on 2)

The composition of claim 2 wherein the oxyalkylene unit OX1 has a molecular weight of about 2,000 to about 40,000.
