Abstract

1326023 Copolyamide BP CHEMICALS INTERNATIONAL Ltd 30 Sept 1970 [24 Oct 1969] 52194/69 Addition to 1228761 Heading C3R In a copolyamide at least 80% of the units are derived from (a) both iso- and tere-phthalic acids, (b) hexamethylene diamine and isophorone diamine, and (c) dodecamethylene diamine or 12-aminododecanoic acid and of these (c) provides 4 to 15% of the total polyamide units, isophorone diamine provides 5 to 50% of the total diamine units, and hexamethylene diamine constitutes at least 50% of the diamine mixture (b). The invention modifies that of the Parent Specification 1,228,761 by including the specified proportion of units (c) to provide improved impact strength. The same preparatory methods, additional units, chain terminators and colour stabilizers as are used in the Parent Specification may be employed and the products have similar uses. Examples describe copolymers from the following molar ratios of the monomers isophthalic acid: terephthalic acid: hexamethylene diamine : isophorone diamine : dodecamethylene diamine : 12-aminododecanoic acid:- (1) and (2) 30 : 20 : 30 : 10 : 10 : 0; (3) 30 : 20 : 22À5 : 12À5 : 15 : 0; (4) 28À5 : 18À9 : 35À8 : 11À9 : 0 : 4À9 and (5) 24À7 : 20À2 : 32À7 : 12 : 0 : 10À4. Ammonium hypophosphite is used as colour stabilizer in all examples and benzoic acid is added as molecular weight regulator in all except Example 3. Reference is made to Specification 1,266,864. Reference has been directed by the Comptroller to Specifications 976,007, 977,868, 1,096,908 and 1,100,972.
