摘要：
A BLOCK COPOLYMER HAVING THE GENERAL FORMULA
A-(B-A)N
IN WHICH A REPRESENTS A CRYSTALLINE POLYMER BLOCK HAVING A MELTING POINT ABOVE 100*C. AND THE TOTAL AMOUNT OF POLYMER BLOCK A IS FROM 3 PERCENT TO 30 PERCENT BY WEIGHT OF THE BLOCK COPOLYMER AND IN WHICH B REPRESENTS AN AMOUPHOUS POLYMER BLOCK HAVING A GLASS TRANSITION TEMPERATURE NOT GREATER THAN 15*C. AND HAS A VISCOSITY AVERAGE MOLECULAR WEIGHT OF 10,000 TO 600,000 AND N IS AN INTEGAR OF FROM 1 TO 5.
