摘要

(A1) statistical being even in the molecule, the isoshianeto basis 2 or more andThe hard segment 2 or more the glass transition temperature is raised as a component of deyuropurasuchitsuku three dimensional building a bridge connection structure (a11), orThe soft segment 2 or more it decreases the glass transition temperature as a component of deyuropurasuchitsuku three dimensional building a bridge connection structureAt least poriisoshianeto of 1 where it contains kinds and,(A2) at least, general system I of 1 kinds: X [ R ( oh) _n] _m (i)[In formula, exponent and variable have the following meaning:n is number 1 - 5,m is 1 or 2,X to display the functional group of isoshianeto reactivity, at the same timeR displays the 2 - 5 connection characteristic organic bases, but when (A1) the soft segment is contained as a condition, R to contain the hard segment 1 (a11) at least, or then it consists] poly- all, mol ratio (A2): (A1) 2 and equivalence ratio [X+OH]: Statistical being even in the production possibility, molecule by reacting with NCO 2, ramification chain poly- all which possesses the hydroxyl basis 2 or more (A), the manufacturing method and its use.
