Title:
POLYETHER ESTER AMIDE TYPE ADHESIVE FOR MEDICAL TREATMENT
Document Type and Number:
Japanese Patent JP3642912
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a new adhesive for medical treatment which has a sufficient adhesion, and is excellent in the stability for an adhering performance, and a function as a sticking preparation, etc.
SOLUTION: A polyether, and polyester, polyamide skeleton is constituted of a polyether ester amide copolymer, which substantially comprises a repeating unit represented by the formula (in this case, A is a binary aromatic group with a number of carbon atoms 6-12, D is a binary hydrocarbon group with a number of carbon atoms 2-15, R is an alkylene group with a number of carbon atoms 2-4, (k) is a unit repeating number wherein a number average molecular weight of a polyoxy alkylene structure represented by (RO)k may become 200-20,000, I is a unit repeating number wherein a number average molecular weight of a polyoxy ethylene structure represented by (CH2CH2O) any become 200-20,000, and R' is an alkyl group of which the number of carbon atoms is in a range of 4-12.), and of which the total content of (3), (5) based on the total amount of the repeating unit represented by (1), (2), (3), (4) and (5) is 20-90wt.% by a weight volume ration, and of which the content of (4) is within a range of 70-5wt.% by a weight volume ratio.
