Abstract
Disclosed are polyesteramide resin compositions having amide units of formula (I): ##STR1## and the units of the formula (II): ##STR2## wherein the polyesteramide is substantially devoid of units derived from butane diol. The ratio of (I) to (II) in the polyesteramide is preferably less than 1:3. Preferred polyesteramides have at least 80% of units of formula (I) separated by at least one of the units of formula (II).
Claims5
A polyesteramide resin composition having units represented by the amide formula (I):
- ##STR15## adjacent units of the ester formula (II):
- ##STR16## according to the following formula:
- ##STR17## wherein R.sub.6 and R.sub.8 are the same and are C.sub.2 or C.sub.6 alkylene provided that R.sub.8 is not butylene, R.sub.7 and R.sub.9 are the same and are a para-phenylene radical, the ratio of e/f is between about 0.05 and 0.5, said polyesteramide resin having a degree of uniformity of greater than 85 percent as determined by the following formula:
- ##EQU2## whereby said resin has a rapid crystallization rates.
