摘要:
A graft macromer, comprising the reaction product of at least one macromer being at least one molecule which comprises in its structure one or more hydroxyl-terminated polyether and/or polyester chains, with at least one grafting compound which comprises in its structure at least one at least monoalkoxylated or at least monohalogenated silyl group and at least one alkyl, cycloalkyl or aryl containing group which is reactive towards the hydroxyl group of the macromer, is used for dispersing e.g. SiO2 in a polyol.
摘要:
The invention relates to a process for preparing a polyamide dispersion in polyol, the polyamide dispersion in polyol thus obtained, the use of a polyether amine in the preparation of the polyamide dispersion in polyol, the use of the polyamide dispersion in polyol for preparing a polyurethane, a respective process and the polyurethane.
摘要:
Stabiliser, comprising the reaction product of at least one macromer with at least one C4-30-alkyl(meth)acrylate in at least one polyether polyol 1 in the presence of at least one free radical polymerisation catalyst and optionally at least one chain transfer agent, the at least one macromer being at least one molecule which comprises in its structure one or more polymerisable double bonds, able to copolymerise with C4-30-alkyl(meth)acrylates and which furthermore comprises in its structure one or more hydroxyl-terminated polyether chains.
摘要:
The invention relates to a process for preparing a dispersion of magnetizable particles in polyol by mechanical mixing of the magnetizable particles at a temperature in the range of from 80 to 260° C., preferably 100 to 220° C., more preferably 160 to 200° C. with a polyol selected from the group consisting of polyesterols or polyether ester polyols having an acid number in the range of from 0.1 to 3.0.
摘要:
Laser-markable foamed pellets contain a composition (MI), containing a thermoplastic elastomer (TPE-1) and a color component as component (c1) selected from laser marking additives. A process can be used for producing said laser-markable foamed pellets. The laser-markable foamed pellets according to the present invention can be used for preparing a laser-markable molded body. A process for preparing a laser-markable molded body involves providing and fusing the laser-markable foal led pellets.
摘要:
A process for preparing a dispersion of inorganic oxide particles in polyester polyol by mechanically mixing of the inorganic oxide particles at a temperature of more than 160° C. with a polyester polyol having an acid number in the range of from 0.05 to 1.5.
摘要:
The present invention relates to a process for preparing a thermoplastic copolymer from polycaprolactam and thermoplastic polyurethane (TPU), to thermoplastic copolymers thus obtained and to shaped articles formed from copolymers of this type.
