Abstract

A composition comprises (a) 40 to 5 per cent by weight of a rubbery organic di-isocyanate modified linear polyester or polyesteramide, and (b) 60 to 95 per cent by weight of a crystalline linear polyester or an organic di-isocyanate modified crystalline linear polyester. The polyester or polyesteramide used for making the rubbery ingredient preferably has a molecular weight of 1000 or more and is made by reacting a glycol (e.g. ethylene-, propylene- or butyleneglycols), a dicarboxylic acid (e.g. succinic, glutaric, adipic, methyl adipic, pimelic or phthalic acid) and if desired a diamine (e.g. ethylene or hexamethylene diamine) or an alkylamine (e.g. monoethanolamine or propanolamine). One mol. of the polyester or polyesteramide is reacted with 1.0-1.2 mols. of the diisocyanate. The crystalline polyester is made by reacting a glycol (e.g. ethylene-, tetramethylene- or hexamethylene glycol) with a dicarboxylic acid (e.g. succinic, adipic, suberic, sebacic or terephthalic acids) and if it is to be reacted with a di-isocyanate (e.g. hexamethylene-, toluylene -, p - phenylene -, 4:41 - diphenylmethane- or naphthalene-di-isocyanate), 1.0-1.2 mols. of di-isocyanate are used per mol. of polyester. The crystalline polyester or di-isocyanate modified crystalline polyester preferably has a molecular weight of greater than 10,000. In examples (1) a polyesteramide derived from adipic acid, ethylene glycol and monoethanolamine) is modified with hexamethylene di-isocyanate and mixed with a hexamethylene di-isocyanate modified polyethylene sebacate to give a composition which may be compression moulded; (2) a naphthylene diisocyanate modified polyethylene adipate is mixed with polyethylene sebacate to give a composition which may be compression moulded. Specification 580,524, [Group IV], is referred to.
