A two-step process for lactic acid polymerization is studied: in the first step the lactic acid is condensation-polymerized to a low-molecular-weight hydroxylterminated prepolymer; and then the molecular weight is raised by joining prepolymer chains together using diisocyanate as the chain extender.
The work reported in the preceding article in this series is extended by consideration of polysiloxane-ceramic composites based on atactic poly(methylphenylsiloxane) (PMPS) elastomers instead of poly(dimethylsiloxane). The former is noncrystallizable because of its stereochemically irregular structu
