Non-hairing moisture curable compositions
Abstract
A mixture of hydroxy functional polymers which can be used to form isocyanate prepolymers which are non-hairing at application temperature are disclosed. Examples of suitable mixtures of hydroxy functional polymers that can be used to form the prepolymers are: (1) linear polyester blends, comprising a first and second polyester wherein each polyester is the reaction product of a polyol and a polyacid, wherein a + b < or = 4, c + d > or = 6 a + b > 4 or ≦ 6, c + d > or = 10 a + b > 6 or ≦ 8, c + d > or = 12 herein a is the number of methylene moieties in the polyol used to form the first polyester, b is the number of methylene moieties in the polyacid used to form the first polyester, c is the number of methylene moieties in the polyol used to form the second polyester of the blend, d is the number of methylene moieties in the polyacid used to form the second polyester of the blend; and(2) a blend of at least one non-linear polyester and one linear polyester, wherein the non-linear polyester is selected from the group consisting of polyneopentyl adipate, polypropylene adipate and polycyclohexanedimethyl adipate, and the linear polyester is selected from the group consisting of polyethylene adipate, polybutylene succinate, and polyhexamethylene sebacate, provided that when the linear polyester is polyhexamethylene sebacate, the non-linear polyester is polyneopentyl adipate or polypropylene adipate; and(3) a blend of poly ε-caprolactone and at least one linear polyester selected from the group consisting of polyethylene adipate, polyethylene succinate and polybutylene succinate.

- 2(2) a mixture of at least one non-linear polyester and a linear polyester, wherein the non-linear polyester is selected from the group consisting of polyneopentyl adipate, polypropylene adipate and polycyclohexanedimethyl adipate, and the linear polyester is selected from the group consisting of polyethylene adipate, polybutylene succinate and polyhexamethylene sebacate, provided that when the linear polyester is polyhexamethylene sebacate, the non-linear polyester is polyneopentyl adipate or polypropylene adipate:and (3) a mixture of poly c-caprolactone and at least one linear polyester selected from the group consisting of polyethylene adipate, polyethylene succinate and polybutylene succinate. (2) en blanding av minst én ikke-lineær polyester og en lineær polyester, hvori den ikke-lineære polyesteren velges fra gruppen bestående av polyneopentyladipat, polypropylenadipat og polycykloheksandimetyladipat, og den lineære polyesteren velges fra gruppen bestående av polyetylenadipat, polybutylensuksinat og polyheksametylensebacat, forutsatt at når den lineære polyesteren er polyheksametylensebacat, er den ikke-lineære polyesteren polyneopentyladipat eller polypropylenadipat: og (3) en blanding av poly c-kaprolakton og minst én lineær polyester valgt fra gruppen bestående av polyetylenadipat, polyetylensuksinat og polybutylensuksinat.

(54) DESCRIPTION OF THE INVENTION NON-TRADING Moisture-hardening blends.
(57) Summary A mixture of hydroxy-functional polymers that can be used to make isocyanate prepolymers which are non-wire forming at the application temperature is described. Examples of suitable mixtures of hydroxy-functional polymers which can be used to form the prepolymers are:
(1) linear polyester blends comprising a first and a second polyester wherein each polyester is the reaction product of a polyol and a polyacid wherein a + b <or = 4, c + d> or = 6 a + b> 4 or in 6, c + d> or = 10 a + b> 6 or 58, c + d> or = 12 wherein a is the number of methylene groups in the polyol used to form the first polyester, b is the number of methylene groups in the polyacid used to form the first polyester, c is the number of methylene groups in the polyol used to form the second polyester in the mixture, d is the number of methylene groups in the polyacid used to form the second polyester in the mixture: and
