帮你查了,可惜我们这不可以看到全文,只有摘要. Thermal and mechanical properties of some caprolactam-poly(propylene oxide) block copolymers Fernanda M. B. Coutinho and Ariosvaldo A. Barbosa Sobrinho Instituto de Macromoleculas, Universidade Federal do Rio de Janeiro, P.O. Box 68525, Rio de Janeiro, RJ 21945, Brazil Received 25 June 1990. Available online 25 April 2003. Abstract Nylon-6 block copolymers with higher impact strength were synthesized using caprolactam as monomer, caprolactam magnesium bromide as catalyst and a telechelic isocyanate-terminated poly(propylene oxide) as macro-activator. various proportions of macro-activator up to 25 wt% were employed in order to examine the influence on the mechanical and thermal properties of the block copolymers. Impact strength increased with increase of macro-activator content but Vicat softening point, Rockwell hardness and crystallization temperature on cooling decreased. Corresponding author. author for correspondence European Polymer Journal Volume 27, Issue 1, 1991, Pages 105-108 第二篇我估计也没有,就不查了 |
